{{Ali}}

'''Ali ibn Abi Talib''' ({{langx|ar|عَلِيُّ بْن أَبِي طَالِب|translit=ʿAlī ibn Abī Ṭālib}}) ({{Circa|600 – {{CE|661}}}}) was the fourth [[Rashidun caliph]] who ruled from {{CE|656}} until [[Assassination of Ali|his assassination]] in 661, as well as the first [[imamate in Shia doctrine|Shia Imam]]. He was the cousin and son-in-law of the Islamic prophet [[Muhammad]]. Born to [[Abu Talib ibn Abd al-Muttalib]] and [[Fatima bint Asad]], Ali was raised by his elder cousin Muhammad and was [[Early Muslims|among the first]] to accept his teachings.

Ali played a pivotal role in the early years of [[Islam]] when [[Muslims]] were severely persecuted in [[Mecca]]. After the immigration ({{Transliteration|ar|[[hijrah|hijra]]}}) to [[Medina]] in 622, Muhammad gave his daughter [[Fatima]] to Ali in marriage and swore a pact of brotherhood with him. Ali served as Muhammad's secretary and deputy in this period, and was the flag bearer of his army. Numerous sayings of Muhammad praise Ali, the most controversial of which was uttered in 632 at the [[Ghadir Khumm]], "Whoever I am his {{Transliteration|ar|[[mawla]]}}, then Ali is his {{Transliteration|ar|mawla}}." The interpretation of the [[polysemous]] [[Arabic]] word {{Transliteration|ar|mawla}} is disputed: For [[Shia Islam|Shia Muslims]], Muhammad thus invested Ali with his religious and political authority, while [[Sunni Islam|Sunni Muslims]] view this as a mere statement of friendship and rapport. When Muhammad died in the same year, a group of Muslims met in the absence of Ali and appointed [[Abu Bakr]] ({{Reign|632|634}}) as their leader. Ali later relinquished his claims to leadership and resigned from public life during the reigns of Abu Bakr and his successor, [[Umar]] ({{Reign|634|644}}). Even though his advice was occasionally sought, the conflicts between Ali and the first two caliphs are epitomized by his refusal to follow their practices. This refusal cost Ali the caliphate to the benefit of [[Uthman]] ({{Reign|644|656}}), who was thus appointed to succeed Umar by the electoral council. Ali was also highly critical of Uthman, who was widely accused of nepotism and corruption. Yet Ali also repeatedly mediated between the caliph and the provincial dissidents angered by his policies.

Following [[Assassination of Uthman|Uthman's assassination]] in June 656, Ali was elected caliph in Medina. He immediately faced two separate rebellions, both ostensibly to avenge Uthman: The triumvirate of [[Talha ibn Ubayd Allah|Talha]], [[Zubayr ibn al-Awwam|Zubayr]], both companions of Muhammad, and his widow [[Aisha]] captured [[Basra]] in [[Lower Mesopotamia|Iraq]] but were defeated by Ali in the [[Battle of the Camel]] in 656. Elsewhere, [[Mu'awiya I|Mu'awiya]], whom Ali had just removed from the governorship of [[Syria (region)|Syria]], fought against Ali the inconclusive [[Battle of Siffin]] in 657, which ended in a failed arbitration process that alienated some of Ali's supporters. These formed the [[Kharijites]], who later terrorized the public and were crushed by Ali in the [[Battle of Nahrawan]] in 658. Ali was assassinated in 661 by the Kharijite dissident [[Ibn Muljam]], which paved the way for Mu'awiya to seize power and found the dynastic [[Umayyad Caliphate]]. 

Ali is revered for his courage, honesty, unbending devotion to Islam, [[magnanimity]], and equal treatment of all Muslims. For his admirers, he has thus become the archetype of uncorrupted Islam and pre-Islamic chivalry. Sunni Muslims regard him as the last of the {{Transliteration|ar|[[Rashidun Caliphate|rashidun]]}} ({{Lit|rightly-guided}}) caliphs, while Shia Muslims venerate him as their first [[Imamate in Shia doctrine|imam]], that is, the rightful religious and political successor to Muhammad. Ali's place is said to be second only to Muhammad in Shia [[Muslim culture]]. The [[Imam Ali Shrine|shrine of Ali]] in [[Najaf]], Iraq, is a major destination for Shia pilgrimage. The legacy of Ali is collected and studied in numerous books, the most famous of which is {{Transliteration|ar|[[Nahj al-balagha]]}}.<!--Do NOT add citations to the lead, except for material likely to be challenged, per [[MOS:LEADCITE]] ([[Wikipedia:Manual of Style/Lead section#Citations)]].

==Birth and early life==

Ali was born in [[Mecca]] to [[Abu Talib ibn Abd al-Muttalib]] and his wife [[Fatimah bint Asad|Fatima bint Asad]] around 600 [[Common Era|CE]].{{sfn|Gleave|2008}} His date of birth is possibly 13 [[Rajab]],{{sfn|Shah-Kazemi|2015b}}{{sfn|Afsaruddin|Nasr|2023}} which is the occasion celebrated annually by [[Shia Islam|Shia Muslims]].{{sfn|Momen|1985|p=239}} Ali may have been the only person born inside the [[Kaaba|Ka'ba]],{{sfn|Afsaruddin|Nasr|2023}}{{sfn|Shah-Kazemi|2015b}}{{sfn|Gleave|2008}} the holiest site of [[Islam]], which is located in Mecca.  Ali's father was a leading member of the [[Banu Hashim]], a clan within the Meccan tribe of [[Quraysh]].{{sfn|Shah-Kazemi|2015b}} Abu Talib also raised his nephew Muhammad after his parents died. Later, when Abu Talib fell into poverty, Ali was taken in at the age of about five and raised by Muhammad and his wife [[Khadija bint Khuwaylid|Khadija]].{{sfn|Afsaruddin|Nasr|2023}}

Aged about eleven,{{sfn|Gleave|2008}} Ali was among the first to accept Muhammad's teachings and profess Islam. Ali did so either after Khadija or after Khadija and Muhammad's successor, [[Abu Bakr]]. While the precise order here is debated among Shia and [[Sunni Islam|Sunni]] scholars,{{sfn|Veccia Vaglieri|2012a}} the earliest sources place Ali before Abu Bakr.{{sfn|Gleave|2008}} Muhammad's call to Islam in Mecca lasted from 610 to 622, during which Ali assiduously supported the small Muslim community, especially the poor.{{sfn|Afsaruddin|Nasr|2023}} Some three years after his first revelation,{{sfn|Rubin|1995|p=130}} Muhammad gathered his relatives for a [[Hadith of warning|feast]], invited them to Islam, and asked for their assistance.{{sfn|Momen|1985|p=12}} Aged about fourteen,{{Sfn|Momen|1985|p=12}}{{Sfn|Abbas|2021|p=34}} Ali was the only relative there who offered his support, after which Muhammad told his guests that Ali was his brother and his successor,{{sfn|Gleave|2008}}{{sfn|Momen|1985|p=12}} according to the Sunni historian [[al-Tabari]] ({{Died in|923}}). The Shia interpretation of this episode is that Muhammad had already designated Ali as his successor.{{sfn|Momen|1985|p=12}}{{sfn|Rubin|1995|pp=136–7}}

== Companionship of Muhammad ==
{{See also|Laylat al-Mabit|Event of the mubahala|Military career of Ali|Hadith of the position|Ghadir Khumm}}

When tipped off about an assassination plot in 622, Muhammad escaped to Yathrib, now known as [[Medina]], but Ali stayed behind as his decoy.{{sfn|Afsaruddin|Nasr|2023}}{{sfn|Huart|2012a}} That Ali risked his life for Muhammad is said to be the reason for the revelation of the [[Quran]]ic passage, "But there is also a kind of man who gives his life away to please God."{{sfn|Mavani|2013|p=71, 98}}{{sfn|Abbas|2021|pp=46, 206}}{{sfn|Shah-Kazemi|2015b}} This emigration marks the beginning of the [[Islamic calendar]] (AH). Ali too escaped Mecca after returning the goods entrusted to Muhammad there.{{sfn|Veccia Vaglieri|2012a}} Later in Medina, Muhammad selected Ali as his brother when he paired [[Muslims]] for [[Brotherhood among the Sahabah|fraternity pacts]].{{sfn|Poonawala|1982}} Around 623–625, Muhammad gave his daughter [[Fatima]] to Ali in marriage,{{sfn|Kassam|Blomfield|2015}}{{sfn|Buehler|2014|p=186}} aged about twenty-two at the time.{{sfn|Afsaruddin|Nasr|2023}} Muhammad had earlier turned down marriage proposals for Fatima by some of his [[Companions of the Prophet|companions]], notably, Abu Bakr and [[Umar]].{{sfn|Klemm|2005|p=186}}{{sfn|Buehler|2014|p=186}}{{sfn|Qutbuddin|2006|p=248}}

===Event of the {{Transliteration|ar|mubahala}}===
{{Main|Event of the mubahala}}

[[File:83_Imam_Ali_searching_of_Doldol_from_Khavaran_Nameh.jpg|thumb|Muhammad and Ali, a folio from the fifteenth century [[Iran]]ian epic ''Khavarannama'']]

A [[Christians|Christian]] envoy from [[Najran]], located in [[South Arabia]], arrived in Medina circa 632 and negotiated a peace treaty with Muhammad.{{Sfn|Momen|1985|pp=13{{ndash}}14}}{{Sfn|Schmucker|2012}} The envoy also debated with Muhammad the nature of [[Jesus]], human or divine.{{Sfn|Madelung|1997|p=16}}{{Sfn|Osman|2015|p=110}} Linked to this episode is verse 3:61 of the Quran,{{sfn|Nasr|Dagli|Dakake|Lumbard|2015|pp=|p=379}} which instructs Muhammad to challenge his opponents to {{Transliteration|ar|mubahala}} ({{Lit|mutual cursing}}),{{Sfn|Haider|2014|p=35}} perhaps when their debate had reached a deadlock.{{Sfn|Osman|2015|p=110}} Even though the delegation ultimately withdrew from the challenge,{{Sfn|Schmucker|2012}} Muhammad appeared for the occasion of {{Transliteration|ar|mubahala}}, accompanied by Ali, his wife Fatima, and their two sons, [[Hasan ibn Ali|Hasan]] and [[Husayn ibn Ali|Husayn]].{{Sfn|Haider|2014|p=36}}{{sfn|Poonawala|1982}} The inclusion of these four by Muhammad in the {{Transliteration|ar|mubahala}} ritual, as his witnesses and guarantors,{{Sfn|McAuliffe|2023}}{{Sfn|Fedele|2018|p=56}} likely raised their religious rank within the community.{{Sfn|Madelung|1997|p=16}}{{sfn|Lalani|2006|p=29}} If the word 'ourselves' in the verse is a reference to Ali and Muhammad, as Shia authors argue, then the former naturally enjoys a similar religious authority in the Quran as the latter.{{Sfn|Mavani|2013|p=72}}{{Sfn|Bill|Williams|2002|p=29}}[[File:Levha (panel) in honor of Imam 'Ali.jpg|thumb|The topmost Arabic text reads, "There is no brave youth except Ali and there is no sword except Zulfiqar"]]

===Political career===
In Medina, Ali acted as Muhammad's secretary and deputy.{{sfn|Momen|1985|p=13}}{{sfn|Veccia Vaglieri|2012a}} He was also one of the scribes tasked with committing the Quran to writing.{{sfn|Afsaruddin|Nasr|2023}} In 628, Ali wrote down the terms of the [[Treaty of al-Hudaybiya]], the peace treaty between Muslims and Meccan pagans. In 630, divine orders pushed Muhammad to replace Abu Bakr with Ali for a key Quranic announcement in Mecca,{{sfn|Momen|1985|p=14}}{{sfn|Shah-Kazemi|2014}} according to the canonical Sunni source {{Transliteration|ar|[[al-Sunan al-Sughra|Sunan al-Nasa'i]]}}.{{sfn|Shah-Kazemi|2015b}} Ali also helped ensure that the [[Conquest of Mecca]] in 630 was bloodless and later destroyed the idols housed in Ka'ba.{{sfn|Afsaruddin|Nasr|2023}} In 631, Ali was sent to preach Islam in [[Yemen (region)|Yemen]],{{sfn|Afsaruddin|Nasr|2023}} as a consequence of which the [[Hamdanids (Yemen)|Hamdanids]] peacefully converted.{{sfn|Huart|2012a}}{{sfn|Shah-Kazemi|2015b}} Ali also peacefully resolved a blood feud between Muslims and the [[Banu Jadhimah|Banu Jadhima]].{{sfn|Shah-Kazemi|2015b}}

Ali accompanied Muhammad in all of his military missions except the [[Expedition of Tabuk]] in 630, during which Ali was left behind in charge of Medina.{{sfn|Huart|2012a}} The [[hadith of the position]] is linked to this occasion, "Are you not content, Ali, to stand to me as [[Aaron in Islam|Aaron]] stood to [[Moses in Islam|Moses]], except that there will be no prophet after me?" This statement appears in the canonical Sunni sources {{transliteration|ar|[[Sahih al-Bukhari]]}} and {{transliteration|ar|[[Sahih Muslim]]}}, among others.{{sfn|Miskinzoda|2015|p=69}} For the Shia, this [[hadith]] signifies Ali's usurped right to succeed Muhammad.{{sfn|Miskinzoda|2015|pp=76–7}} In the absence of Muhammad, Ali commanded the expedition to [[Expedition of Ali ibn Abi Talib (Fadak)|Fadak]] in 628.{{sfn|Veccia Vaglieri|2012a}}{{sfn|Afsaruddin|Nasr|2023}}
[[File:Hazrat Ali slays Marhab.JPG|thumb|220x220px|Ali in the Battle of Khaybar]]
Ali was renowned for his bravery on the battlefield,{{sfn|Poonawala|1982}}{{sfn|Veccia Vaglieri|2012a}} and for his magnanimity towards his defeated enemies.{{sfn|Shah-Kazemi|2019|p=46}} He was the [[standard-bearer]] in the [[Battle of Badr]] (624) and the [[Battle of Khaybar]] (628).{{sfn|Momen|1985|p=13}} He vigorously defended Muhammad in the [[Battle of Uhud]] (625) and the [[Battle of Hunayn]] (630),{{sfn|Poonawala|1982}}{{sfn|Afsaruddin|Nasr|2023}} and Muslims' victory in the Battle of Khaybar has been attributed to his courage,{{sfn|Veccia Vaglieri|2012a}} where he is said to have torn off the iron gate of the enemy fort.{{sfn|Poonawala|1982}} Ali also defeated the pagan champion [[Amr ibn Abd al-Wud|Amr ibn Abd Wudd]] in the [[Battle of the Trench]] in 627.{{sfn|Shah-Kazemi|2015b}} According to al-Tabari,{{sfn|Shah-Kazemi|2015b}} Muhammad reported hearing a divine voice at Uhud, "[There is] no sword but [[Zulfiqar]] [Ali's sword], [there is] no chivalrous youth ({{Transliteration|ar|fata}}) but Ali."{{sfn|Shah-Kazemi|2014}}{{sfn|Afsaruddin|Nasr|2023}} Ali and another companion, [[Zubayr ibn al-Awwam|Zubayr]], apparently oversaw the killing of the [[Banu Qurayza]] men for treachery in 626{{Ndash}}627,{{sfn|Veccia Vaglieri|2012a}} though the historicity of this account has been doubted.{{sfn|Faizer|2006}}{{sfn|Donner|2010|pp=72–3}}{{sfn|Arafat|1976}}

===Ghadir Khumm===
[[File:Chronology of Ancient Nations, f.162r miniature.jpg|thumb|The Investiture of Ali at the Ghadir Khumm ([[MS Arab 161]], fol. 162r, 1307–8 [[Ilkhanid]] manuscript illustration)]]
On his return trip from the [[Farewell Pilgrimage|Hajj pilgrimage in 632]], Muhammad halted the large caravan of pilgrims at the [[Ghadir-e Khumm|Ghadir Khumm]] and addressed them after the [[Congregational prayer (Islam)|congregational prayer]].{{sfn|Dakake|2007|pp=34–9}} After the prayer,{{Sfn|Mavani|2013|p=79}} Muhammad delivered a sermon to a large number of Muslims in which he emphasized the importance of the [[Quran]] and his {{Transliteration|ar|[[ahl al-Bayt|ahl al-bayt]]}} ({{Lit|people of the house}}, his family).{{Sfn|Amir-Moezzi|2014}}{{Sfn|Momen|1985|p=16}}{{Sfn|Mavani|2013|p=80}}{{Sfn|Veccia Vaglieri|2012b}} Taking Ali by the hand, Muhammad then asked if he was not {{transliteration|ar|awla}} ({{Lit|have more authority over|closer to}}) the believers than themselves,{{Sfn|Veccia Vaglieri|2012b}}{{Sfn|Lalani|2000|p=70–71}} this is evidently a reference to verse 33:6 of the Quran.{{Sfn|Dakake|2007|p=34}}{{Sfn|Lalani|2000|p=71}} When they affirmed,{{Sfn|Veccia Vaglieri|2012b}} Muhammad then declared, "He whose {{transliteration|ar|[[mawla]]}} I am, Ali is his {{transliteration|ar|mawla}}."{{sfn|Dakake|2007|pp=34–7}}{{sfn|Veccia Vaglieri|2012b}} {{Transliteration|ar|[[Musnad Ahmad ibn Hanbal|Musnad Ibn Hanbal]]}}, a canonical Sunni source, adds that Muhammad repeated this statement three or four more times and that Umar congratulated Ali after the sermon, "You have now become the {{Transliteration|ar|mawla}} of every faithful man and woman."{{sfn|Momen|1985|p=15}}{{sfn|Mavani|2013|p=80}} Muhammad had earlier alerted Muslims about his impending death.{{sfn|Veccia Vaglieri|2012d}}{{sfn|Amir-Moezzi|2014}}{{sfn|Jones|2009}} Shia sources describe the event in greater detail, linking the announcement to verses 5:3 and 5:67 of the Quran.{{sfn|Veccia Vaglieri|2012d}}

The authenticity of the Ghadir Khumm is rarely contested,{{sfn|Veccia Vaglieri|2012b}}{{sfn|Mavani|2013|p=20}}{{sfn|Dakake|2007|p=35}}{{sfn|Amir-Moezzi|2014}} as its "among the most extensively acknowledged and substantiated" reports in classical Islamic sources.{{sfn|Lalani|2011}} However, ''{{transliteration|ar|mawla}}'' is a [[polysemous]] Arabic word and its interpretation in the context of the Ghadir Khumm is split along sectarian lines. Shia sources interpret ''{{transliteration|ar|mawla}}'' as 'leader', 'master', and 'patron',{{Sfn|Jafri|1979|p=20}} while Sunni sources interpret it as love or support for Ali.{{sfn|Afsaruddin|Nasr|2023}}{{sfn|Dakake|2007|p=45}} Shias, therefore, view the Ghadir Khumm as the investiture of Ali with Muhammad's religious and political authority,{{sfn|Mavani|2013|p=2}}{{sfn|Dakake|2007|p=47}}{{sfn|Shah-Kazemi|2015b}} while Sunnis regard it as a statement about the rapport between the two men,{{sfn|Afsaruddin|Nasr|2023}}{{sfn|Amir-Moezzi|2014}}{{sfn|Jafri|1979|p=21}} or that Ali should execute Muhammad's will.{{sfn|Afsaruddin|Nasr|2023}} Shias point to the extraordinary nature of the announcement,{{sfn|Dakake|2007|p=45}} give Quranic and textual evidence,{{sfn|Mavani|2013|p=70}}{{sfn|Veccia Vaglieri|2012d}}{{sfn|Amir-Moezzi|2014}} and argue to eliminate other meanings of {{Transliteration|ar|mawla}} in the hadith except for authority,{{sfn|Dakake|2007|p=46}} while Sunnis minimize the importance of the Ghadir Khumm by casting it as a simple response to earlier complaints about Ali.{{sfn|Dakake|2007|pp=44–5}} During his [[caliphate]], Ali is known to have asked Muslims to come forward with their testimonies about the Ghadir Khumm,{{sfn|Lalani|2006|p=590}}{{sfn|Madelung|1997|p=253}}{{sfn|McHugo|2017|loc=§2.IV}} presumably to counter challenges to his legitimacy.{{sfn|Dakake|2007|p=41}}

====Saqifa====
Muhammad died in 632 when Ali was in his early thirties.{{Sfn|Afsaruddin|2013|p=51}} As he and other close relatives prepared for the burial,{{sfn|Jafri|1979|p=39}}{{sfn|Momen|1985|p=18}} a group of the [[Ansar (Islam)|Ansar]] (Medinan natives, {{Literal translation|helpers}}) gathered at the [[Saqifah|Saqifa]] to discuss the future of Muslims or to retake control of their city, Medina. Abu Bakr and Umar were among the few representatives of the [[Muhajirun]] (Meccan converts, {{Literal translation|migrants}}) at the Saqifa.{{sfn|Madelung|1997|pp=30–2}} The case of Ali was unsuccessfully brought up at the Saqifa in his absence,{{sfn|Jafri|1979|p=37}}{{sfn|Madelung|1997|p=35}} and, ultimately, those present there appointed Abu Bakr to leadership after a heated debate that is said to have become violent.{{sfn|Madelung|1997|pp=31–33}} Clan rivalries at the Saqifa played a key role in favor of Abu Bakr,{{sfn|Jafri|1979|p=39}}{{Sfn|Momen|1985|pp=18–9}} and the outcome may have been different in a broad council ([[Shura|{{transliteration|ar|shura}}]]) with Ali as a candidate.{{sfn|Madelung|1997|pp=36, 40}}{{sfn|McHugo|2017|loc=§1.III}} In particular, the Quraysh tradition of hereditary succession strongly favored Ali,{{sfn|Madelung|1997|p=5}}{{sfn|Mavani|2013|p=34}}{{sfn|Keaney|2021|loc=§3.1}} even though his youth weakened his case.{{sfn|Veccia Vaglieri|2012a}}{{Sfn|Afsaruddin|2013|p=51}} By contrast, the succession (caliphate) of Abu Bakr is often justified on the basis that he led some of the prayers in Muhammad's final days,{{sfn|Jafri|1979|p=39}}{{sfn|Walker|2014|p=3}} but the veracity and political significance of such reports have been questioned.{{sfn|Jafri|1979|p=39}}{{sfn|Lecomte|2012}}{{sfn|Shaban|1971|p=16}}

While the appointment of Abu Bakr was met with little resistance in Medina,{{sfn|Walker|2014|p=3}} the Banu Hashim and some companions of Muhammad soon gathered in protest at Ali's house.{{sfn|Khetia|2013|pp=31–2}}{{sfn|Madelung|1997|p=32}} Among them were Zubayr and Muhammad's uncle [[Abbas ibn Abd al-Muttalib|Abbas]].{{sfn|Madelung|1997|p=32}} These protestors held Ali to be the rightful successor to Muhammad,{{sfn|Buehler|2014|p=186}}{{sfn|Fedele|2018}} probably in reference to the Ghadir Khumm.{{sfn|Amir-Moezzi|2014}} Among others,{{sfn|Madelung|1997|p=43}} al-Tabari reports that Umar then led an armed mob to Ali's residence and threatened to set the house on fire if Ali and his supporters did not pledge their allegiance to Abu Bakr.{{sfn|Jafri|1979|p=40}}{{sfn|Buehler|2014|p=186}}{{sfn|Qutbuddin|2006|p=249}}{{sfn|Cortese|Calderini|2006|p=8}} The scene soon grew violent,{{sfn|Madelung|1997|p=43}}{{sfn|Jafri|1979|p=41}} but the mob retreated after Ali's wife, Fatima, pleaded with them.{{sfn|Jafri|1979|p=40}} Abu Bakr later placed a successful boycott on the Banu Hashim,{{sfn|Madelung|1997|pp=43–4}} who eventually abandoned their support for Ali.{{sfn|Madelung|1997|pp=43–4}}{{sfn|Jafri|1979|pp=40–1}} Most likely, Ali himself did not pledge his allegiance to Abu Bakr until Fatima died within six months of her father, Muhammad.{{sfn|Soufi|1997|p=86}} In Shia sources, the death (and miscarriage) of the young Fatima are attributed to an [[Attack on Fatima's house|attack on her house]] to subdue Ali by the order of Abu Bakr.{{sfn|Khetia|2013|p=78}}{{sfn|Buehler|2014|p=186}}{{sfn|Fedele|2018}} Sunnis categorically reject these reports,{{sfn|Abbas|2021|p=98}} but there is evidence in their early sources that a mob entered Fatima's house by force and arrested Ali,{{Sfn|Soufi|1997|p=|pp=84–5}}{{Sfn|Ayoub|2014|pp=17–20}}''{{sfn|Khetia|2013|p=35}}'' an incident that Abu Bakr regretted on his deathbed.{{Sfn|Soufi|1997|p=84}}{{sfn|Khetia|2013|p=38}} Likely a political move to weaken the Banu Hashim,{{sfn|Jafri|1979|p=47}}{{sfn|Madelung|1997|p=50}}{{sfn|Mavani|2013|p=116}}{{sfn|Soufi|1997|pp=104–105}} Abu Bakr had earlier confiscated from Fatima the rich lands of Fadak, which she considered her inheritance (or a gift) from her father.{{Sfn|Sajjadi|2018}}{{Sfn|Veccia Vaglieri|2012c}} The confiscation of Fadak is often justified in Sunni sources with a hadith about [[Hadith of Muhammad's inheritance|prophetic inheritance]], the authenticity of which has been doubted partly because it contradicts Quranic injunctions.{{sfn|Sajjadi|2018}}{{sfn|Soufi|1997|p=100}}

===Caliphate of Abu Bakr (r. 632–634)===
In the absence of popular support, Ali eventually accepted the temporal rule of Abu Bakr, probably for the sake of Muslim unity.{{sfn|Madelung|1997|p=141}}{{sfn|Momen|1985|pp=19–20}}{{sfn|McHugo|2017|p=40}} In particular, Ali turned down proposals to forcefully pursue the caliphate.{{sfn|Jafri|1979|p=44}}{{sfn|Veccia Vaglieri|2012a}} He nevertheless viewed himself as the most qualified candidate for leadership by virtue of his merits and his kinship with Muhammad.{{sfn|Madelung|1997|pp=141, 253}}{{sfn|Mavani|2013|p=113{{ndash}}114}}{{sfn|Momen|1985|p=62}} Evidence suggests that Ali further considered himself as the designated successor of Muhammad.{{sfn|Mavani|2013|pp=114, 117}}{{sfn|Madelung|1997|p=253}}{{sfn|Shah-Kazemi|2019|p=79}} Unlike Muhammad's lifetime,{{sfn|Anthony|2013}}{{sfn|Mavani|2013|p=117}} Ali retired from public life during the caliphates of Abu Bakr and his successors, Umar and [[Uthman]].{{sfn|Afsaruddin|Nasr|2023}}{{sfn|Anthony|2013}}{{Sfn|Poonawala|1982}} Ali did not participate in the [[Ridda wars]] and the [[early Muslim conquests]],{{Sfn|Poonawala|1982}} though he remained an advisor to Abu Bakr and Umar on government and religious matters.,{{sfn|Afsaruddin|Nasr|2023}}{{sfn|Poonawala|1982}} However, their conflicts with Ali is also well-documented,{{sfn|Aslan|2005|p=122}}{{sfn|Madelung|1997|pp=42, 52–54, 213–4}}{{sfn|Abbas|2021|p=94}} but largely ignored in Sunni sources.{{sfn|Jafri|1979|p=45}}{{sfn|Shah-Kazemi|2019|p=78}} These tensions were epitomized during the proceedings of the electoral council in 644 when Ali refused to be bound by the precedence of the first two caliphs.{{sfn|Mavani|2013|p=117}}{{sfn|Anthony|2013}} In contrast, Shia sources view Ali's pledge to Abu Bakr as a (coerced) act of political expediency ({{transliteration|ar|[[taqiya]]}}).{{sfn|Shah-Kazemi|2019|p=81}} The conflicts with Ali are probably magnified in Shia sources.{{Sfn|Jafri|1979|p=45}}

===Caliphate of Umar (r. 634–644)===
Before his death in 634, Abu Bakr designated Umar as his successor.{{Sfn|Dakake|2007|p=50}} Ali was not consulted about this appointment, which was initially resisted by some senior companions.{{Sfn|Jafri|1979|pp=47–8}} Ali himself did not press any claims this time and kept aloof from public affairs during the caliphate of Umar,{{sfn|Momen|1985|p=20}} who nevertheless consulted Ali in certain matters.{{sfn|Afsaruddin|Nasr|2023}}{{sfn|Veccia Vaglieri|2012a|p=382}} For instance, Ali is credited with the idea of adopting the migration to Medina ([[Hijrah|{{Transliteration|ar|hijra}}]]) as the beginning of the Islamic calendar.{{Sfn|Huart|2012a}} Yet Ali's political advice was probably ignored.{{sfn|Veccia Vaglieri|2012a}} For example, Umar devised a state register ({{Transliteration|ar|[[dewan|diwan]]}}) to distribute excess state revenues according to Islamic precedence,{{Sfn|Afsaruddin|2013|p=32}} but Ali held that those revenues should be equally distributed among Muslims, following the practice of Muhammad and Abu Bakr.{{Sfn|Ayoub|2014|p=32}}{{sfn|Veccia Vaglieri|2012a}} Ali was also absent from the strategic meeting of notables near [[Damascus]].{{sfn|Veccia Vaglieri|2012a}} Ali did not participate in Umar's military expeditions,{{Sfn|Jafri|1979|p=46}}{{sfn|Gleave|2008}} although he does not seem to have publicly objected to them.{{sfn|Gleave|2008}} Umar likely opposed the combination of prophethood and caliphate in the Banu Hashim,{{sfn|Glassé|2001|p=40}}{{Sfn|Tabatabai|1975|p=158}} and he thus [[Hadith of Pen and Paper|prevented Muhammad]] from dictating his will on his deathbed,{{Sfn|Momen|1985|p=16}}{{sfn|Abbas|2021|p=89}}{{sfn|Madelung|1997|p=22}} possibly fearing that he might expressly designate Ali as his successor.{{sfn|Madelung|1997|pp=66–7}} Nevertheless, perhaps realizing the necessity of Ali's cooperation in his collaborative scheme of governance, Umar made some limited overtures to Ali and the Banu Hashim during his caliphate.{{sfn|Madelung|1997|pp=62, 65}} For instance, Umar returned Muhammad's estates in Medina to Ali, but kept Fadak and Khayber.{{sfn|Madelung|1997|pp=62–64}} By some accounts, Umar also insisted on marrying Ali's daughter [[Umm Kulthum bint Ali|Umm Kulthum]], to which Ali reluctantly agreed when the former enlisted public support for his demand.{{sfn|Madelung|1997|p=67}}

==== Election of Uthman (644) ====
[[File:Balami - Tarikhnama - the election of 'Othman as the caliphate of Medina (cropped).jpg|thumb|The election of Uthman, a folio from ''[[Tarikhnama]]'']]
Before his death in 644,{{sfn|Pellat|1983}} Umar tasked a small committee with choosing the next caliph among themselves.{{sfn|Jafri|1979|p=50}} Ali and Uthman were the strongest candidates in this committee,{{Sfn|Jafri|1979|p=52}}{{Sfn|Ayoub|2014|p=43}} whose members were all early companions of Muhammad from the Quraysh tribe.{{sfn|Jafri|1979|p=50}} Another member, [[Abd al-Rahman ibn Awf]], was given the deciding vote either by the committee or by Umar.{{Sfn|Madelung|1997|p=71}}{{Sfn|Jafri|1979|p=51}}{{Sfn|Momen|1985|p=21}} After deliberations, Ibn Awf appointed his brother-in-law Uthman as the next caliph,{{Sfn|Jafri|1979|p=54}}{{Sfn|Kennedy|2016|p=60}} when the latter promised to follow the precedent of the first two caliphs.{{Sfn|Jafri|1979|p=54}} By contrast, Ali rejected this condition,{{Sfn|Jafri|1979|p=54}}{{Sfn|Momen|1985|p=21}} or gave an evasive answer.{{Sfn|Keaney|2021|loc=§3.4}} The Ansar were not represented in the committee,{{Sfn|Shaban|1971|pp=62–3}}{{Sfn|Jafri|1979|p=51}} which was evidently biased toward Uthman.{{sfn|Madelung|1997|pp=71–2}}{{Sfn|Jafri|1979|p=|pp=52–3}}{{sfn|Momen|1985|p=21}} Both of these factors worked against Ali,{{Sfn|Jafri|1979|p=51}}{{Sfn|Abbas|2021|p=116}}{{Sfn|Madelung|1997|p=68}} who could have not been simply excluded from the proceedings.{{Sfn|Jafri|1979|p=|pp=52{{ndash}}53, 55}}

===Caliphate of Uthman (r. 644–656)===
Uthman was widely accused of nepotism,{{Sfn|Madelung|1997|p=87}} corruption,{{Sfn|Veccia Vaglieri|1970|p=67}}{{Sfn|Shah-Kazemi|2019|p=84}} and injustice.{{Sfn|Dakake|2007|p=52}} Ali too criticized Uthman's conduct,{{Sfn|Veccia Vaglieri|2012a}}{{Sfn|Gleave|2008}}{{Sfn|Madelung|1997|p=|pp=108, 113}} including his lavish gifts for his kinsmen.{{Sfn|Jafri|1979|p=53}}{{Sfn|Madelung|1997|p=108}} Ali also protected outspoken companions, such as [[Abu Dharr al-Ghifari|Abu Dharr]] and [[Ammar ibn Yasir|Ammar]],{{Sfn|Hinds|1972a|p=467}}{{Sfn|Madelung|1997|p=109}} and overall acted as a restraining influence on Uthman.{{Sfn|Hinds|1972a|p=467}} Some supporters of Ali were part of the opposition movement,{{Sfn|Jafri|1979|p=63}}{{Sfn|Daftary|2014|p=30}} joined in their efforts by [[Talha ibn Ubayd Allah|Talha]] and Zubayr, both senior companions of Muhammad, and by his widow [[A'isha|Aisha]].{{Sfn|Madelung|1997|p=98}}{{Sfn|Madelung|1997|pp=100–2}}{{Sfn|Jafri|1979|p=63}} Among such supporters of Ali were [[Malik al-Ashtar]] and other religiously learned {{Transliteration|ar|qurra}} ({{Lit|Quran readers}}).'''{{Sfn|Jafri|1979|p=59}}'''{{Sfn|Madelung|1997|p=108}} These supporters wanted to see Ali as the next caliph but there is no evidence that he coordinated with them.{{Sfn|Madelung|1997|pp=107–8}} Ali also rejected the requests to lead the rebels,{{Sfn|Veccia Vaglieri|2012a}}{{Sfn|Momen|1985|p=22}} although he probably sympathized with their grievances.{{Sfn|Jafri|1979|p=62}}{{Sfn|Momen|1985|p=22}} He was therefore considered a natural focus for the opposition,{{Sfn|McHugo|2017|p=49}} at least morally.{{Sfn|Veccia Vaglieri|2012a}}

==== Assassination of Uthman (656) ====
As their grievances mounted, provincial dissidents poured into Medina in 656.{{Sfn|Poonawala|1982}} The [[Egypt]]ian opposition sought the advice of Ali, who urged them to negotiate with Uthman.{{Sfn|Madelung|1997|p=121}}{{Sfn|Madelung|1997|pp=118–9}} Ali similarly asked the [[Lower Mesopotamia|Iraqi]] opposition to refrain from violence, which they heeded.{{Sfn|Madelung|1997|p=128}} He also repeatedly mediated between Uthman and the dissidents,{{Sfn|Poonawala|1982}}{{Sfn|Anthony|2013|p=31}}{{Sfn|Madelung|1997|p=111}} to address their economical and political grievances.{{Sfn|Veccia Vaglieri|1970|p=68}}{{Sfn|Poonawala|1982}} In particular, Ali negotiated and guaranteed the agreement that ended the first siege.{{Sfn|Madelung|1997|pp=111, 119}}{{Sfn|Poonawala|1982}} He then convinced Uthman to publicly repent,{{Sfn|Madelung|1997|p=122}} but the caliph soon retracted his statement, possibly pressed by his secretary [[Marwan I|Marwan ibn al-Hakam]].{{Sfn|Madelung|1997|p=123}} Egyptian rebels laid siege to Uthman's residence for a second time when they intercepted an official letter ordering their punishment. They demanded the caliph's abdication but he refused and maintained his innocence about the letter,{{Sfn|Madelung|1997|p=112}} for which Marwan is often blamed in the early sources.{{sfn|Madelung|1997|p=127}}{{sfn|Levi Della Vida|Khoury|2012}} Ali also sided with Uthman,{{Sfn|Madelung|1997|p=112}} but the caliph apparently accused him about the letter.{{Sfn|Madelung|1997|p=126}} This is probably when Ali refused to further intercede for Uthman,{{Sfn|Madelung|1997|p=112}}{{Sfn|McHugo|2017|p=49}} who was assassinated soon afterward by Egyptian rebels.{{Sfn|Madelung|1997|p=127}}{{Sfn|Hinds|1972a}}{{Sfn|Donner|2010|p=152}} Ali played no role in the deadly attack,{{Sfn|Veccia Vaglieri|2012a}}{{Sfn|Kennedy|2016|p=65}} and his son [[Hasan ibn Ali|Hasan]] was injured while guarding Uthman's besieged residence at the request of Ali.{{Sfn|Afsaruddin|Nasr|2023}}{{Sfn|Veccia Vaglieri|2012f}}{{Sfn|Jafri|1979|p=63}} He also convinced the rebels to deliver water to Uthman's house during the siege.{{Sfn|Madelung|1997|p=112}}{{Sfn|Hinds|1972a|p=467}}

When Uthman was assassinated in 656 by Egyptian rebels,{{Sfn|Madelung|1997|p=127}} the potential candidates for caliphate were Ali and Talha. The Umayyads had fled Medina, leaving the provincial rebels and the Ansar in control of the city. Among the Egyptians, Talha enjoyed some support, but the Iraqis and most of the Ansar supported Ali.{{sfn|Madelung|1997|p=141}} The majority of the Muhajirun,{{Sfn|Poonawala|1982}}{{Sfn|Momen|1985|p=22}}{{Sfn|Donner|2010|p=157}} and key tribal figures also favored Ali at this time.{{Sfn|Lapidus|2002|p=56}} The caliphate was offered by these groups to Ali, who, after some hesitation,{{Sfn|Momen|1985|p=22}}{{Sfn|Poonawala|1982}}{{Sfn|Gleave|2008}} publicly took the oath of office.{{Sfn|Ayoub|2014|p=81}}{{Sfn|Bahramian|2015}}{{sfn|Madelung|1997|pp=142–3}} Malik al-Ashtar might have been the first to pledge his allegiance to Ali.{{sfn|Madelung|1997|pp=142–3}} Talha and Zubayr, who both aspired to the caliphate,{{Sfn|Momen|1985|p=24}}{{Sfn|Ayoub|2014|p=70}} also gave their pledges to Ali, most likely willingly,{{Sfn|Gleave|2008}}{{Sfn|Madelung|1997|p=143}}{{sfn|Veccia Vaglieri|2012f}} but later broke their oaths.{{Sfn|Madelung|1997|p=147}}{{Sfn|Gleave|2008}}{{Sfn|Jafri|1979|p=64}} Ali probably did not force anyone to pledge,{{Sfn|Ayoub|2014|p=81}} and there is little evidence of any violence, even though many broke with Ali later, claiming that they had pledged under duress.{{Sfn|Madelung|1997|pp=144–5}} At the same time, the supporters, who were in majority in Medina, might have intimidated others.{{Sfn|Madelung|1997|p=144}}

==== Legitimacy ====

Ali thus filled the power vacuum created by the regicide.{{Sfn|Shaban|1971|p=71}}{{Sfn|Anthony|2013|p=31}}{{Sfn|Ayoub|2014|p=85}} His election, irregular and without a council,{{sfn|Madelung|1997|p=141}} faced little public opposition in Medina,{{Sfn|Kennedy|2016|p=65}}{{Sfn|Veccia Vaglieri|1970|p=69}}{{Sfn|Shaban|1971|p=71}} but the rebels' support for him left him exposed to accusations of complicity in Uthman's assassination.{{Sfn|Veccia Vaglieri|2012a}} Even though underprivileged groups readily rallied around Ali,{{sfn|Shaban|1971|p=72}}{{sfn|Momen|1985|p=24}} he had limited support among the powerful Quraysh, some of whom aspired to caliphate.{{Sfn|Donner|2010|p=158}}{{sfn|Madelung|1997|p=141}} Within the Quraysh, two camps opposed Ali: the Umayyads, who believed that the caliphate was their right after Uthman, and those who wished to restore the caliphate of Quraysh on the same principles laid by Abu Bakr and Umar. This second group was likely the majority within the Quraysh.{{Sfn|Madelung|1997|p=147}}{{Sfn|Kennedy|2016|p=65}} Ali was indeed vocal about the divine prerogative of Muhammad's kin to leadership,{{Sfn|Keaney|2021|loc=§3.5}}{{Sfn|Madelung|1997|p=72}} which would have jeopardized the political ambitions of the rest of the Quraysh.{{Sfn|Abbas|2021|p=115}}

==== Justice ====
The caliphate of Ali was characterized by his strict justice.{{sfn|Madelung|1997|pp=309–10}}{{sfn|Momen|1985|p=25}}{{Sfn|Poonawala|1982}} He implemented radical policies to restore his vision of prophetic governance,{{Sfn|Tabatabai|1975|p=43}}{{Sfn|McHugo|2017|p=53}}{{Sfn|Ayoub|2014|p=91}} and dismissed nearly all of Uthman's governors,{{Sfn|Donner|2010|p=158}} whom he considered corrupt.{{Sfn|Madelung|1997|p=148}} Ali also distributed the treasury funds equally among Muslims, following the practice of Muhammad,{{Sfn|Tabatabai|1975|p=45}} and is said to have shown zero tolerance for corruption.{{Sfn|Shah-Kazemi|2019|p=105}}{{Sfn|Madelung|1997|p=272}} Some of those affected by Ali's egalitarian policies soon revolted against him under the pretext of revenge for Uthman.{{Sfn|Tabatabai|1975|p=44}} Among them was [[Mu'awiya I|Mu'awiya]], the incumbent governor of [[Syria]].{{Sfn|Daftary|2014|p=30}} Ali has therefore been criticized by some for political naivety and excessive rigorism,{{Sfn|Veccia Vaglieri|2012a}}{{Sfn|Madelung|1997|p=|pp=149–50}} and praised by others for righteousness and lack of political expediency.{{Sfn|Tabatabai|1975|p=44}}{{Sfn|Ayoub|2014|p=91}} His supporters identify similar decisions of Muhammad,{{Sfn|Shah-Kazemi|2019|p=89}}{{Sfn|Tabatabai|1975|p=46}} and argue that Islam never allows for compromising on a just cause, citing verse 68:9 of the Quran,{{Sfn|Tabatabai|1975|p=46}} "They wish that thou might compromise and that they might compromise."{{Sfn|Tabatabai|1975|p=64}}{{sfn|Nasr|Dagli|Dakake|Lumbard|2015|p=3203}} Some instead suggest that Ali's decisions were actually justified on a practical level.{{Sfn|Bahramian|2015}}{{Sfn|Shah-Kazemi|2019|pp=89–90}}{{Sfn|Poonawala|1982}} For instance, the removal of unpopular governors was perhaps the only option available to Ali because injustice was the main grievance of the rebels.{{Sfn|Bahramian|2015}}

==== Religious authority ====
As evident from his public speeches,{{Sfn|Madelung|1997|p=150}} Ali viewed himself not only as the temporal leader of the Muslim community but also as its exclusive religious authority.{{Sfn|Shah-Kazemi|2019|p=77}}{{Sfn|Shaban|1971|p=73}} He thus laid claim to the religious authority to interpret the Quran and [[Sunnah|Sunna]].{{sfn|Shaban|1971|pp=72–73}}{{Sfn|Mavani|2013|pp=67–68}} Some supporters of Ali indeed held him as their divinely-guided leader who deserved the same type of loyalty that Muhammad did.{{Sfn|Dakake|2007|p=57}} They felt an absolute and all-encompassing bond of spiritual loyalty ({{Transliteration|ar|walaya}}) to Ali that transcended politics.{{Sfn|Haider|2014|p=34}} For instance, many of them publicly offered Ali their unconditional support circa 658.{{Sfn|Dakake|2007|pp=|p=60}}{{Sfn|Madelung|1997|pp=251{{ndash}}252}} They justified their absolute loyalty to Ali on the basis of his merits, precedent in Islam,{{Sfn|Dakake|2007|p=59}} his kinship with Muhammad,{{Sfn|Jafri|1979|p=71}} and also the announcement by the latter at the Ghadir Khumm.{{Sfn|Haider|2014|p=34}} Many of these supporters also viewed Ali as the rightful successor to Muhammad after his death,{{Sfn|Dakake|2007|pp=58–59}} as evidenced in the poetry from that period, for instance.{{Sfn|Dakake|2007|p=262n30}}{{Sfn|Jafri|1979|p=67}}

Ali opposed centralized control over provincial revenues.{{sfn|Lapidus|2002|p=56}} He equally distributed excess taxes and booty among Muslims,{{sfn|Lapidus|2002|p=56}}{{sfn|Veccia Vaglieri|2012a}} following the precedent of Muhammad and Abu Bakr.{{sfn|Abbas|2021|p=133}}{{Sfn|Tabatabai|1975|p=45}} In comparison, Umar had distributed the state revenues according to perceived Islamic merit,{{Sfn|Shah-Kazemi|2019|p=90}}{{Sfn|Ayoub|2014|p=83}} and Uthman was widely accused of nepotism and corruption.{{Sfn|Madelung|1997|p=87}}{{Sfn|Shah-Kazemi|2019|p=|pp=84, 90}}{{Sfn|Veccia Vaglieri|1970|p=67}} The strictly egalitarian policies of Ali earned him the support of underprivileged groups, including the Ansar, the {{Transliteration|ar|qurra}}, and the late immigrants to Iraq.{{sfn|Shaban|1971|p=72}} By contrast, Talha and Zubayr were both Qurayshite companions of Muhammad who had amassed immense wealth under Uthman.{{Sfn|Jafri|1979|pp=55–6}} They both revolted against Ali when he refused to grant them favors.{{Sfn|Ayoub|2014|p=94}}{{Sfn|Tabatabai|1975|p=45}} Some other figures among the Quraysh similarly turned against Ali,{{Sfn|Ayoub|2014|p=95}}{{Sfn|McHugo|2017|p=64}} who even withheld public funds from his relatives,{{sfn|Madelung|1997|p=264}}{{Sfn|Shah-Kazemi|2019|pp=105–6}} whereas his archenemy Mu'awiya readily offered bribes.{{Sfn|McHugo|2017|p=64}}{{Sfn|Madelung|1997|p=276}} Ali instructed his officials to collect tax payments on a voluntary basis and without harassment, and to prioritize the poor when distributing public funds.{{Sfn|Abbas|2021|p=153}} A letter attributed to Ali directs his governor to pay more attention to land development than taxation.{{sfn|Lambton|1991|pp=xix, xx}}{{Sfn|Abbas|2021|p=156}}

==== Rules of war ====
During the Muslim civil war, Ali forbade his soldiers from looting,{{sfn|Heck|2023}}{{Sfn|Shah-Kazemi|2019|p=94}} and instead paid them from tax revenues.{{sfn|Heck|2023}} He also pardoned his enemies in victory.{{Sfn|Shah-Kazemi|2019|p=94}}{{Sfn|Ayoub|2014|p=84}} Both of these practices were later enshrined in [[Fiqh|Islamic law]].{{Sfn|Shah-Kazemi|2019|p=94}} Ali also advised his commander al-Ashtar not to reject any calls to peace, not to violate any agreements,{{Sfn|Shah-Kazemi|2019|p=115}} and ordered him not to commence hostilities.{{Sfn|Ayoub|2014|p=109}} Ali similarly barred his troops from disturbing civilians,{{Sfn|Ayoub|2014|p=108}} killing the wounded and those who fled, mutilating the dead, entering homes without permission, looting, and harming women.{{Sfn|Ayoub|2014|p=|pp=109–10}} He prevented the enslavement of women in victory, even though some protested.{{Sfn|Veccia Vaglieri|2012a}} Before the [[Battle of Siffin]] with Mu'awiya, Ali did not retaliate and allowed his enemies to access drinking water when he gained the upper hand.{{sfn|Madelung|1997|p=227}}{{Sfn|Ayoub|2014|pp=111–2}}

===Battle of the Camel===

Aisha publicly campaigned against Ali immediately after his accession.{{Sfn|Ayoub|2014|p=89}}{{Sfn|Donner|2010|p=158}} She was joined in Mecca by her close relatives, Talha and Zubayr,{{Sfn|Madelung|1997|p=133}} who thus broke their earlier oaths of allegiance to Ali.{{Sfn|Madelung|1997|p=147}}{{Sfn|Gleave|2008}}{{Sfn|Jafri|1979|p=64}} This opposition demanded the punishment of Uthman's assassins,{{Sfn|Cappucci|2014|p=19}}{{Sfn|Anthony|2013|p=31}} and accused Ali of complicity in the assassination.{{Sfn|Anthony|2013|p=31}}{{Sfn|Madelung|1997|p=147}}{{Sfn|Poonawala|1982}} They also called for the removal of Ali from office and for a Qurayshite council to appoint his successor.{{Sfn|Donner|2010|p=158}}{{Sfn|Madelung|1997|p=157}} Their primary goal was likely the removal of Ali, rather than vengeance for Uthman,{{Sfn|Madelung|1997|p=157}}{{Sfn|Aslan|2005|p=132}}{{Sfn|McHugo|2017|loc=§2.II}} against whom the triumvirate had stirred up public opinion.{{Sfn|Veccia Vaglieri|2012f}}{{Sfn|Madelung|1997|p=|pp=98, 101, 107}}{{Sfn|Ayoub|2014|p=88}} The opposition failed to gain enough traction in [[Hijaz|Hejaz]],{{sfn|Poonawala|1982}}{{sfn|Veccia Vaglieri|2012a}} and instead captured [[Basra]] in Iraq,{{sfn|Gleave|2008}}{{sfn|Poonawala|1982}} killing many there. Ali raised an army from nearby [[Kufa]],{{sfn|Veccia Vaglieri|2012f}}{{sfn|Hinds|1971|p=361}} which formed the core of Ali's forces in the coming battles.{{sfn|Hinds|1971|p=361}} The two armies soon camped just outside of Basra,{{sfn|Madelung|1997|p=166}}{{sfn|Poonawala|1982}} both probably numbered around ten thousand men.{{sfn|Hazleton|2009|p=107}} After three days of failed negotiations,{{sfn|Madelung|1997|p=169|pp=}} the two sides readied for battle.{{sfn|Madelung|1997|p=169}}{{sfn|Poonawala|1982}}{{sfn|Gleave|2008}}

==== Account of the battle ====
The battle took place in December 656.{{Sfn|Donner|2010|p=159}}{{sfn|Madelung|1997|pp=169–70}} The rebels commenced hostilities,{{sfn|Veccia Vaglieri|2012f}}{{sfn|Madelung|1997|p=170}} and Aisha was present on the battlefield, riding in an armored palanquin atop a red camel, after which the battle is named.{{sfn|Hazleton|2009|p=113}}{{sfn|Abbas|2021|p=139}} Talha was soon killed by another rebel, Marwan, the secretary of Uthman.{{sfn|Madelung|1997|pp=171–2}}{{sfn|Abbas|2021|p=140}} Zubayr, an experienced fighter, deserted shortly after the battle had begun,{{sfn|Madelung|1997|p=170}}{{sfn|Veccia Vaglieri|2012f}} but was pursued and killed.{{Sfn|Madelung|1997|p=170}}{{Sfn|Veccia Vaglieri|2012f}} His desertion suggests he had serious moral misgivings about their cause.{{sfn|Madelung|1997|p=171}}{{sfn|Veccia Vaglieri|2012f}} Ali won the day,{{Sfn|Veccia Vaglieri|2012f}}{{Sfn|Madelung|1997|p=172}}{{Sfn|Bahramian|2015}} and Aisha was respectfully escorted back to Hejaz.{{sfn|Abbas|2021|p=141}}{{Sfn|Veccia Vaglieri|2012f}}{{Sfn|Donner|2010|p=159}} Ali then announced a public pardon,{{sfn|Hazleton|2009|p=121}} setting free all war prisoners, even Marwan,{{sfn|Madelung|1997|p=180-1}}{{sfn|Abbas|2021|p=141}} and prohibiting the enslavement of their women. Their seized properties were also returned.{{Sfn|Hazleton|2009|p=122}} Ali then stationed himself in Kufa,{{Sfn|Madelung|1997|p=182}} which thus became his de facto capital.{{Sfn|Donner|2010|p=159}}{{Sfn|McHugo|2017|loc=§2.II}}

===Battle of Siffin===
[[File:First Fitna Map, Ali-Muawiya Phase.png|thumb|Map of the [[First Fitna]]; green territory under Ali's control; pink territory under Mu'awiya's control.]] [[File:Balami - Tarikhnama - Battle of Siffin (cropped).jpg|thumb|right|Combat between the forces of Ali and Mu'awiya during the Battle of Siffin, from the ''[[Tarikhnama]]'']]
Mu'awiya, the incumbent governor of Syria, was deemed corrupt and unfit by Ali,{{Sfn|Madelung|1997|p=148}} who wrote to and removed him from his post.{{Sfn|Madelung|1997|p=194}}{{Sfn|Petersen|1958|p=165}}{{Sfn|Ayoub|2014|p=97}} In turn, Mu'awiya, as Uthman's cousin, launched a propaganda campaign across Syria, blaming Ali for the regicide and calling for revenge.{{Sfn|Madelung|1997|p=190}}{{Sfn|Abbas|2021|p=144}}{{Sfn|Rahman|1995|p=58}} Mu'awiya also joined forces with [[Amr ibn al-As]],{{Sfn|Donner|2010|p=160}} a military strategist,{{Sfn|Ayoub|2014|p=99}} who pledged to back the Umayyads against Ali in return for life-long governorship of Egypt.{{Sfn|Madelung|1997|p=196}} Yet Mu'awiya also secretly offered to recognize the caliphate of Ali in return for Syria and Egypt,{{Sfn|Madelung|1997|p=203}} which Ali rejected.{{Sfn|Madelung|1997|p=204}} Mu'awiya then formally declared war, charging Ali with regicide, demanding his removal, and a Syrian council thereafter to elect the next caliph.{{Sfn|Madelung|1997|pp=204–205}} Contemporary authors tend to view Mu'awiya's call for revenge as a pretext for a power grab.{{Sfn|Shah-Kazemi|2014|p=23}}{{Sfn|Shaban|1971|p=73}}{{Sfn|Shah-Kazemi|2019|pp=95–6}}{{Sfn|Madelung|1997|p=186}}{{Sfn|Kennedy|2016|p=66}}{{Sfn|McHugo|2017|loc=2.III}}

==== Account of the battle ====
In the summer of 657, the armies of Ali and Mu'awiya camped at Siffin, west of the [[Euphrates|Euphrates River]],{{Sfn|Madelung|1997|p=226}} numbering perhaps at 100,000 and 130,000, respectively.{{Sfn|Lecker|2012}} Many of Muhammad's companions were present in Ali's army, whereas Mu'awiya could only boast a handful.{{Sfn|Momen|1985|p=25}}{{Sfn|Lecker|2012}} The two sides negotiated for a while, to no avail,{{Sfn|Anthony|2013|p=31}}{{Sfn|Donner|2010|p=161}}{{Sfn|Poonawala|1982}}{{Sfn|Shaban|1971|p=75}}{{Sfn|Kennedy|2016|p=67}} after which the main battle took place from Wednesday, 26 July 657,{{Sfn|McHugo|2017|loc=2.III}}{{Sfn|Shah-Kazemi|2014|p=23}} until Friday or Saturday morning.{{sfn|Madelung|1997|p=232}}{{sfn|Donner|2010|p=161}} Ali probably refrained from initiating hostilities,{{Sfn|Bahramian|2015}} and later fought alongside his men on the frontline, whereas Mu'awiya led from his pavilion,{{sfn|Hazleton|2009|p=198}}{{sfn|Madelung|1997|p=234}} and rejected a proposal to settle the matters in a personal duel with Ali.{{Sfn|Madelung|1997|p=235}}{{Sfn|McHugo|2017|loc=2.III}}{{Sfn|Ayoub|2014|p=119}} Among those killed fighting for Ali was Ammar.{{Sfn|Madelung|1997|p=234}} In canonical Sunni sources, a prophetic hadith predicts Ammar's death at the hands of {{Transliteration|ar|al-fi'a al-baghiya}} ({{Lit|rebellious aggressive group}}) who call to hellfire.{{Sfn|Abbas|2021|p=149}}{{Sfn|Lecker|2012}}{{Sfn|Donner|2010|p=161}}

==== Call to arbitration ====
Fighting stopped when some Syrians raised pages of the Quran on their lances, shouting, "Let the Book of God be the judge between us."{{Sfn|Madelung|1997|p=238}}{{Sfn|Donner|2010|p=161}} Since Mu'awiya had for long insisted on battle, this call for arbitration suggests that he now feared defeat.{{Sfn|Madelung|1997|p=238}}{{Sfn|Anthony|2013|p=31}}{{Sfn|Adamec|2017|p=406}} By contrast, Ali exhorted his men to fight, telling them that raising Qurans was for deception, but to no avail.{{Sfn|Madelung|1997|p=238}}{{Sfn|McHugo|2017|loc=2.III}} Through their representatives, the {{Transliteration|ar|qurra}} and the {{Transliteration|ar|[[Ridda Wars|ridda]]}} tribesmen of Kufa,{{Sfn|Veccia Vaglieri|1970|p=70}}{{Sfn|Shaban|1971|p=75}}{{Sfn|Donner|2010|p=161}} the largest bloc in Ali's army,{{Sfn|Poonawala|1982}}{{Sfn|Shaban|1971|p=75}} both threatened Ali with mutiny if he did not answer the Syrians' call.{{Sfn|Madelung|1997|p=238}}{{Sfn|Poonawala|1982}}{{Sfn|Ayoub|2014|pp=123–4}}{{Sfn|Hinds|1972b|p=97}} Facing strong peace sentiments in his army, Ali accepted the arbitration proposal,{{sfn|Madelung|1997|p=241}} most likely against his own judgment.{{sfn|Donner|2010|p=161}}{{Sfn|Madelung|1997|p=241}}

==== Arbitration agreement ====
Mu'awiya now proposed that representatives from both sides should find a Quranic resolution.{{Sfn|Poonawala|1982}}{{Sfn|Hinds|1972b|p=98}} Mu'awiya was represented by his ally Amr,{{sfn|Madelung|1997|pp=241–2}} whereas, despite Ali's opposition, the majority in his camp pressed for the neutral Abu Musa, the erstwhile governor of Kufa.{{sfn|Afsaruddin|2013|p=53}}{{sfn|Donner|2010|p=161}}{{Sfn|Dakake|2007|p=|pp=1–2}} The arbitration agreement was written and signed on 2 August 657,{{sfn|Madelung|1997|p=243}} stipulating that the two representatives should meet on neutral territory,{{Sfn|Dakake|2007|p=1}} adhere to the Quran and Sunna, and restore peace.{{sfn|Madelung|1997|p=243}}{{Sfn|Shah-Kazemi|2014|p=23}} Both armies left the battlefield after the agreement.{{sfn|Madelung|1997|p=247}} The arbitration agreement thus divided Ali's camp, as many did not support his negotiations with Mu'awiya, whose claims they considered fraudulent. By contrast, the agreement strengthened Mu'awiya's position, who was now an equal contender for the caliphate.{{Sfn|Madelung|1997|p=245}}

==== Formation of the Kharijites ====
[[File:Iraq under the Abbasid Caliphate (cropped).png|thumb|The [[Nahrawan Canal]] ran parallel to the east bank of the [[Tigris]]]]

Some of Ali's men left him in protest to the arbitration agreement.{{Sfn|Madelung|1997|p=247}}{{Sfn|Bahramian|2015}} Many of them eventually rejoined Ali,{{Sfn|Rauf|2007|p=191}}{{Sfn|Madelung|1997|p=248–249}}{{sfn|Donner|2010|p=163}}{{sfn|Veccia Vaglieri|2012a}} while the rest gathered in the town of [[al-Nahrawan]].{{Sfn|Bahramian|2015}} They became known as the [[Kharijites]] ({{lit|seceders}}), who later took up arms against Ali in the [[Battle of Nahrawan]].{{sfn|Levi Della Vida|2012}}{{sfn|Donner|2010|p=162}}{{sfn|Poonawala|1982}} The Kharijites, many of whom belonged to the {{Transliteration|ar|qurra}},{{Sfn|Hinds|1972b|p=100}} were likely disillusioned with the arbitration process.{{Sfn|Hinds|1972b|p=101}}{{Sfn|Poonawala|1982}} Their slogan was, "No judgment but that of God,"{{Sfn|Shah-Kazemi|2014|p=23}} highlighting their rejection of arbitration (by men) in reference to the Quranic verse 49:9.{{Sfn|Rauf|2007|p=|pp=190–191}} Ali called this slogan a word of truth by which the seceders sought falsehood because he viewed the ruler as indispensable in the conduct of religion.{{Sfn|Madelung|1997|pp=249–50}}

==== Arbitration proceedings ====
The two arbitrators met together in [[Dumat al-Jandal]],{{Sfn|Ayoub|2014|p=129}} perhaps in February 658.{{Sfn|Poonawala|1982}} There they reached the verdict that Uthman had been killed wrongfully and that Mu'awiya had the right to seek revenge.{{sfn|Madelung|1997|p=255}}{{sfn|Aslan|2005|p=137}}{{sfn|Poonawala|1982}} They could not agree on anything else.{{Sfn|Madelung|1997|p=256}} Rather than a judicial ruling, this was a political concession by Abu Musa, who probably hoped that Amr would later reciprocate this gesture.{{sfn|Madelung|1997|p=256}} Ali denounced the conduct of the two arbitrators as contrary to the Quran and began organizing a second Syria campaign.{{sfn|Madelung|1997|p=257}}{{Sfn|Veccia Vaglieri|2012a}} Solely an initiative of Mu'awiya,{{Sfn|Madelung|1997|p=255}} there was also a second meeting in [[Udhruh]].{{Sfn|Madelung|1997|p=255}}{{Sfn|Bahramian|2015}} The negotiations there also failed,{{sfn|Madelung|1997|p=257}} as the two arbitrators could not agree on the next caliph: Amr supported Mu'awiya,{{Sfn|Poonawala|1982}} while Abu Musa nominated his son-in-law Abd Allah ibn Umar,{{Sfn|Poonawala|1982}}{{Sfn|Glassé|2001|p=40}} who stood down.{{Sfn|Poonawala|1982}}{{Sfn|Madelung|1997|p=286}} At its closure, Abu Musa publicly deposed both Mu'awiya and Ali and called for a council to appoint his successor per earlier agreements with Amr. When Amr took the stage, however, he deposed Ali and appointed Mu'awiya as his successor.{{sfn|Glassé|2001|p=40}}{{sfn|Donner|2010|p=165}}{{sfn|Poonawala|1982}} The Kufan delegation reacted furiously to Abu Musa's concessions,{{sfn|Madelung|1997|p=257}} and the common view is that the arbitration failed,{{Sfn|Madelung|1997|p=255}}{{sfn|Afsaruddin|2013|p=53}} or was inconclusive.{{Sfn|Fadel|2013|p=43}}{{Sfn|Rauf|2007|p=191}}{{Sfn|Hinds|1972b|p=102}} It nevertheless strengthened the Syrians' support for Mu'awiya and weakened the position of Ali.{{sfn|Madelung|1997|p=255}}{{sfn|Jafri|1979|p=65}}{{sfn|Momen|1985|p=25}}{{sfn|Poonawala|1982}}{{Sfn|Daftary|2013|p=31}}

===Battle of Nahrawan===

After the arbitration, Mu'awiya received the Syrians' pledge as caliph.{{sfn|Madelung|1997|pp=257–8}} Ali then organized a new, much smaller,{{sfn|Poonawala|1982}} Syria campaign.{{sfn|Donner|2010|p=163}}{{sfn|Glassé|2001|p=40}}{{sfn|Madelung|1997|pp=255, 257}} But he postponed the expedition,{{sfn|Madelung|1997|pp=259–60}} and instead marched to Nahrawan with his army,{{sfn|Madelung|1997|pp=259–60}} when he learned that the Kharijites were interrogating and executing civilians.{{sfn|Wellhausen|1901|pp=17–18}}{{sfn|Madelung|1997|p=254}} They killed many, apparently not even sparing women.{{Sfn|Levi Della Vida|2012}} Ali convinced many of the Kharijites to separate from their army, leaving about 1,500{{Ndash}}1,800, or 2,800, out of about 4,000 fighters.{{sfn|Madelung|1997|p=260}}{{sfn|Wellhausen|1901|p=18}} The rest of the Kharijites then attacked and were crushed by Ali's army of about 14,000 men.{{sfn|Madelung|1997|pp=259–261}}{{sfn|Wellhausen|1901|p=18}} The battle took place either on 17 July 658,{{Sfn|Madelung|1997|pp=260–1}}{{sfn|Donner|2010|p=163}} or in 657.{{sfn|Wellhausen|1927|p=85}}{{Sfn|Madelung|1997|pp=260–1}} Ali has been criticized by some for killing his erstwhile allies,{{Sfn|Ayoub|2014|p=|pp=141, 171}}{{sfn|Donner|2010|p=164}}{{Sfn|Madelung|1997|p=262}} many of whom were outwardly pious Muslims. For others, subduing the Kharijites was necessary, for they were violent and radicalized rebels who posed a danger to Ali's base in Kufa.{{Sfn|Madelung|1997|p=261}}{{Sfn|Kelsay|1993|p=87}}{{Sfn|Afsaruddin|2013|p=53}}{{Sfn|Shah-Kazemi|2019|pp=97–8}}

===Final years===
Following the Battle of Nahrawan, Ali could not muster enough support for a second Syria campaign.{{Sfn|Ayoub|2014|pp=|p=141}}{{Sfn|Madelung|1997|p=262}} Perhaps his soldiers were demoralized,{{sfn|Donner|2010|p=164}} or perhaps they were recalled by their tribal leaders,{{Sfn|Shaban|1971|p=77}}{{Sfn|Jafri|1979|p=123}} many of whom had been bribed and swayed by Mu'awiya.{{Sfn|Kennedy|2016|p=68}}{{Sfn|Jafri|1979|p=123}}{{sfn|Donner|2010|p=164}} By contrast, Ali did not grant any financial favors to tribal chiefs as a matter of principle.{{Sfn|Ayoub|2014|p=95}}{{Sfn|McHugo|2017|p=64}} At any rate, the secession of so many of the {{Transliteration|ar|qurra}} and the coolness of the tribal leaders weakened Ali.{{Sfn|Shaban|1971|p=77}}{{Sfn|Anthony|2013|p=31}}{{Sfn|Kennedy|2016|p=69}} Ali consequently lost Egypt to Mu'awiya in 658.{{Sfn|Donner|2010|p=165}}{{Sfn|Madelung|1997|p=|pp=268{{ndash}}9}} Mu'awiya also began dispatching military detachments,{{sfn|Donner|2010|p=165}} which targeted civilians along the Euphrates river, near Kufa, and most successfully, in the Hejaz and Yemen.{{sfn|Madelung|1997|pp=262, 288–291, 293}} Ali could not mount a timely response to these assaults.{{sfn|Veccia Vaglieri|2012a}} He eventually found sufficient support for a second Syria offensive, set to commence in late winter 661. His success was in part due to the public outrage over Syrian raids.{{Sfn|Madelung|1997|p=307}} However, plans for a second campaign were abandoned after the [[assassination of Ali]].{{sfn|Donner|2010|p=166}}

Ali was assassinated during the [[Fajr prayer|morning prayer]] on 28 January 661 (19 [[Ramadan (calendar month)|Ramadan]] 40 AH) at the [[Great Mosque of Kufa]]. The other given dates are 26 and 30 January. He was struck over his head by the Kharijite dissident [[Ibn Muljim|Ibn Muljam]] with a poison-coated sword,{{Sfn|Veccia Vaglieri|2012g}} in revenge for their defeat in the Battle of Nahrawan.{{Sfn|Madelung|1997|p=308}} Ali died from his wounds about two days later, aged sixty-two or sixty-three. By some accounts, he had long known about his fate by premonition or through Muhammad.{{Sfn|Veccia Vaglieri|2012g}}

Before his death, Ali requested either a meticulous application of {{Transliteration|el|[[lex talionis]]}} to Ibn Muljam or his pardon. At any rate, Ibn Muljam was later executed by Hasan, the eldest son of Ali.{{Sfn|Veccia Vaglieri|2012g}}

Fearing that his body might be exhumed and profaned by his enemies, Ali's burial place was kept a secret and remains uncertain.{{sfn|Veccia Vaglieri|2012a}} Several sites are mentioned as containing Ali's remains, including the [[Imam Ali Shrine|shrine of Ali]] in [[Najaf]] and the [[shrine of Ali]] in [[Mazar, Afghanistan|Mazar]].{{Sfn|Kohlberg|1982}} The former site was identified during the reign of the [[Abbasid Caliphate|Abbasid]] caliph [[Harun al-Rashid]] ({{Reign|786|809}}) and the town of Najaf developed around it, which has become a major destination for Shia pilgrimage.{{Sfn|Veccia Vaglieri|2012a}} The present shrine was built by the [[Safavid Iran|Safavid]] monarch [[Safi of Persia|Safi]] ({{Reign|1629|1642}}),{{Sfn|Momen|1985|p=26}} near which lies an immense cemetery for Shias who wished to be buried next to their [[Imamate in Shia doctrine|imam]].{{Sfn|Veccia Vaglieri|2012a}} Najaf is also home to top religious colleges and prominent Shia scholars.{{Sfn|Veccia Vaglieri|2012a}}{{sfn|Gleave|2008}} Other sites for Ali's burial are claimed to be [[Baghdad]], [[Damascus]], [[Medina]], [[Rayy|Ray]] while a minority of Shias believe it be somewhere in the city of [[Kufa]].{{Sfn|Kohlberg|1982}}

When Ali died, his son Hasan was acknowledged as the next caliph in Kufa.{{sfn|Wellhausen|1901|p=18}}{{sfn|Veccia Vaglieri|2012e}} As Ali's legatee, Hasan was the obvious choice for the Kufans, especially because Ali was vocal about the exclusive right of Muhammad's kin to leadership.{{sfn|Madelung|1997|p=311}}{{sfn|Veccia Vaglieri|2012e}} Most surviving companions of Muhammad were in Ali's army, and they also pledged their allegiance to Hasan,{{sfn|Momen|1985|pp=26–7}}{{sfn|Jafri|1979|p=91}} but overall the Kufans' support for Hasan was likely weak.{{sfn|Momen|1985|p=27}}{{sfn|Jafri|1979|pp=109–10}} Hasan later [[Hasan–Muawiya treaty|abdicated]] in August 661 to Mu'awiya when the latter marched on Iraq with a large force.{{sfn|Momen|1985|p=27}}{{sfn|Jafri|1979|pp=109–10}} Mu'awiya thus founded the dynastic [[Umayyad Caliphate]]. Throughout his reign, he persecuted the family and supporters of Ali,{{Sfn|Madelung|1997|p=334}}{{sfn|Lewis|2012}} and mandated [[Umayyad tradition of cursing Ali|regular public cursing of Ali]].{{Sfn|Madelung|1997|p=334}}{{sfn|Dakake|2007|pp=67,78}}

==Descendants of Ali==

{{See also|Muhsin ibn Ali|Hasanids|Husaynids|Twelvers|Isma'ilism|Kaysanites|Zaydism}}
The first marriage of Ali was to Fatima, who bore him three sons, Hasan, Husayn, and [[Muhsin ibn Ali|Muhsin]].{{Sfn|Lewis|2012}} Muhsin either died in infancy,{{sfn|Buehler|2014|p=186}} or Fatima miscarried him when she was injured in a [[Attack on Fatima's house|raid]] on her house during the succession crisis.{{sfn|Khetia|2013|p=78}} The descendants of Hasan and Husayn are known as the [[Hasanids]] and the [[Husaynids]], respectively.{{Sfn|Daftary|2014}} As the progeny of Muhammad, they are honored in Muslim communities by nobility titles such as {{Transliteration|ar|[[sharif]]}} and {{Transliteration|ar|[[sayyid]]}}.{{sfn|Afsaruddin|Nasr|2023}} Ali and Fatima also had two daughters, [[Zaynab bint Ali|Zaynab]] and [[Umm Kulthum bint Ali|Umm Kulthum]].{{Sfn|Huart|2012b}} After [[Burial of Fatima|Fatima's death]] in 632, Ali remarried multiple times and had more children, including [[Muhammad al-Awsat ibn Ali|Muhammad al-Awsat]] and [[Abbas ibn Ali]].{{Sfn|Huart|2012b}} In his life, Ali fathered seventeen daughters, and eleven, fourteen, or eighteen sons,{{Sfn|Lewis|2012}} among whom, Hasan, Husayn, and [[Muhammad ibn al-Hanafiyya]] played a historical role.{{sfn|Veccia Vaglieri|2012a}} Descendants of Ali are known as the [[Alids]].{{Sfn|Daftary|2014}}

=== Under the Umayyads (661{{Ndash}}750) ===
Mu'awiya succeeded Ali in 661 and founded the dynastic Umayyad Caliphate,{{Sfn|Madelung|2003}} during which Alids were severely persecuted.{{Sfn|Huart|2012b}} After Ali, his followers ({{Transliteration|ar|shi'a}}) recognized his eldest son Hasan as their imam. When he died in 670, likely poisoned at the instigation of Mu'awiya,{{sfn|Momen|1985|p=28}}{{sfn|Madelung|2003}}{{Sfn|Anthony|2013|p=216}} the Shia community followed Hasan's younger brother Husayn, who was killed by Umayyad forces in the [[Battle of Karbala]] in 680, alongside many of his relatives.{{Sfn|Daftary|2014}} To revenge the Karbala massacre, soon followed in 685 the Shia uprising of [[Mukhtar al-Thaqafi|al-Mukhtar]], who claimed to represent Ibn al-Hanafiyya.{{Sfn|Daftary|2014}} The main movements that followed this uprising were the now-extinct [[Kaysanites]] and the Imamites.{{Sfn|McHugo|2017|p=104}} The Kaysanites mostly followed [[Abd Allah ibn Muhammad ibn al-Hanafiyya|Abu Hashim]], the son of Ibn al-Hanafiya. When Abu Hashim died around 716, this group largely aligned itself with the Abbasids, that is, the descendants of Muhammad's uncle Abbas.{{Sfn|Daftary|2014}}{{Sfn|Momen|1985|p=69}} On the other hand, the Imamites were led by quiescent descendants of Husayn, through his only surviving son, [[Ali ibn Husayn Zayn al-Abidin|Ali Zayn al-Abidin]] ({{Died in|713}}). An exception was Ali's son [[Zayd ibn Ali|Zayd]], who led a failed uprising against the Umayyads around 740.{{Sfn|Daftary|2014}} For his followers, known as the [[Zaydism|Zaydites]], any learned Hasanid or Husaynid who rose against tyranny qualified as imam.{{Sfn|Momen|1985|p=|pp=49, 50}}

=== Under the Abbasids (750{{Ndash}}1258) ===
Alids were also persecuted under the [[Abbasid Caliphate|Abbasids]], who toppled the Umayyads in 750.{{Sfn|Daftary|2014}}{{Sfn|Momen|1985|p=71}} Some of the Alids thus revolted,{{Sfn|Lewis|2012}} while some established regional dynasties in remote areas.{{Sfn|Daftary|2014}}{{Sfn|Donner|1999|p=26}} In particular, through imprisonment or surveillance, the Abbasids removed the imams of the Imamites from public life,{{Sfn|Sachedina|1981|p=25}}{{Sfn|Dakake|2007|p=211}} and they are thought to be responsible for the imams' deaths.{{Sfn|Pierce|2016|p=44}}{{Sfn|Momen|1985|p=44}} Mainstream Imamites were the antecedents of the [[Twelver Shi'ism|Twelvers]],{{Sfn|McHugo|2017|p=107}} who believe that their twelfth and final imam, [[Muhammad al-Mahdi]], was born around 868,{{Sfn|Momen|1985|p=161}} but was hidden from the public in 874 for fear of persecution. He remains in occultation by divine will until his reappearance at the end of time to eradicate injustice and evil.{{Sfn|Amir-Moezzi|1998}}{{Sfn|McHugo|2017|p=108}} The only historic split among the Imamites happened when their sixth imam, [[Ja'far al-Sadiq]], died in 765.{{Sfn|Daftary|2014}}{{Sfn|McHugo|2017|p=107}} Some claimed that his designated successor was his son [[Isma'il ibn Ja'far|Isma'il]], who had predeceased al-Sadiq. These were the antecedents of the [[Isma'ilism|Isma'ilites]],{{Sfn|Daftary|2014}} who found political success at the turn of the tenth century,{{Sfn|Haider|2014|p=92}} as the [[Fatimid Caliphate]] in Egypt and the [[Qarmatians]] in [[Eastern Arabia|Bahrain]].{{Sfn|Daftary|2007|pp=2, 110, 128}}

{{Transliteration|ar|Nahj al-balagha}} ({{Lit|the path of eloquence}}) is an eleventh-century collection of sermons, letters, and sayings, all attributed to Ali, compiled by [[Al-Sharif al-Radi|Sharif al-Radi]] ({{Died in|1015}}), a prominent Twelver scholar.{{sfn|Thomas|2008}}{{Sfn|Esposito|2003|p=227}} Because of its sometimes sensitive content, the authenticity of {{Transliteration|ar|Nahj al-balagha}} has long been polemically debated. However, by tracking its content in earlier sources, recent academic research has attributed most of {{Transliteration|ar|Nahj al-balagha}} to Ali.{{sfn|Shah-Kazemi|2006}}{{sfn|Djebli|2012}} The book, particularly its letter of [[Letter of Ali ibn Abi Talib to Malik al-Ashtar|instructions]] addressed at al-Ashtar,{{sfn|Gleave|2008}} has served as an ideological basis for Islamic governance.{{sfn|Esposito|2003|p=227}} The book also includes detailed discussions about social responsibilities, emphasizing that greater responsibilities result in greater rights.{{sfn|Esposito|2003|p=227}} {{Transliteration|ar|Nahj al-balagha}} also contains sensitive material, such as sharp criticism of Ali's predecessors in its [[Shaqshaqiya sermon]],{{sfn|Gleave|2008}} and disapproval of Aisha, Talha, and Zubayr, who had revolted against Ali.{{sfn|Thomas|2008}}{{Sfn|Dakake|2007|p=225}} Celebrated as an example of the most eloquent Arabic,{{Sfn|Gleave|2008}} {{Transliteration|ar|Nahj al-balagha}} has significantly influenced the Arabic literature and rhetoric.{{Sfn|Shah-Kazemi|2006}} Numerous commentaries have been written about the book, including the comprehensive work of the [[Mu'tazilism|Mu'tazilite]] scholar [[Ibn Abi'l-Hadid|Ibn Abil-Hadid]] ({{Died in|1258}}).{{sfn|Gleave|2008}}

{{Transliteration|ar|[[Ghurar al-hikam wa durar al-kalim]]}} ({{Literal translation|exalted aphorisms and pearls of speech}}) was compiled by [[Abd al-Wahid Amidi|Abd al-Wahid al-Amidi]] ({{Died in|1116}}), who was either a [[Shafiʽi school|Shafi'i]] jurist or a Twelver scholar. The book contains thousands of short sayings of Ali on piety and ethics.{{sfn|Shah-Kazemi|2007|p=4}}{{sfn|Gleave|2008}} These aphorisms and other works attributed to Ali have considerably influenced the [[Sufism|Islamic mysticism]].{{Sfn|Jozi|Shah-Kazemi|2015}}

=== ''{{Transliteration|ar|Kitab Ali}}'' ===
{{Transliteration|ar|[[Kitab Ali]]}} ({{Literal translation|book of Ali}}) is a non-extant collection of prophetic sayings gathered by Ali. The book may have concerned matters of lawfulness ([[halal|{{transliteration|ar|halal}}]]) and unlawfulness ([[haram|{{transliteration|ar|haram}}]]), including a detailed penal code. ''{{Transliteration|ar|Kitab Ali}}'' is also often linked to {{Transliteration|ar|[[al-Jafr (book)|al-Jafr]]}}, which is said to contain the esoteric teachings of Muhammad for his household.{{sfn|Esposito|2003|pp=175–176}}{{sfn|Modarressi|2003|p=5}} Copies of ''{{Transliteration|ar|Kitab Ali}}'' were likely available until the early eighth century, and parts of it have survived in later Shia and Sunni works.{{Sfn|Pakatchi|2015}}

===Other works===

== Contributions to Islamic sciences ==
{{Main article|Ali and Islamic sciences}}

The standard recitation of the Quran has been traced back to Ali,{{Sfn|Modarressi|2003|p=3}}{{sfn|Hulmes|2008|p=45}}{{Sfn|Momen|1985|p=25}} and his written legacy is dotted with Quranic commentaries.{{Sfn|Pakatchi|2015}} [[Ibn Abbas]], a leading early exegete, credited Ali with his interpretations of the Quran.{{Sfn|Lalani|2006|p=28}} Ali also related several hundred prophetic hadiths.{{Sfn|Pakatchi|2015}} He is further credited with the first systematic evaluations of hadiths, and is often considered a founding figure for hadith sciences.{{Sfn|Pakatchi|2015}} Ali is also regarded by some as the founder of [[Kalam|Islamic theology]], and his sayings contain the first rational proofs of the [[Tawhid|unity of God]] ({{Transliteration|ar|tawhid}}) in Islam.{{sfn|Nasr|2006|p=|pp=2, 120}}{{sfn|Shah-Kazemi|2014}} In later [[Islamic philosophy]], Ali's sayings and sermons were mined for metaphysical knowledge.{{sfn|Afsaruddin|Nasr|2023}} In particular, {{Transliteration|ar|Nahj al-balagha}} is a vital source for Shia philosophical doctrines, after the Quran and Sunna.{{Sfn|Corbin|2006|pp=35{{ndash}}36}} As a Shia imam, statements and practices attributed to Ali are widely studied in Shia Islam, where they are viewed as the continuation of prophetic teachings.{{Sfn|Pakatchi|2015}}

Often praised for his piety and courage,{{Sfn|Momen|1985|p=25}}{{Sfn|Shah-Kazemi|2019|p=72}}{{Sfn|Veccia Vaglieri|2012a}} Ali fought to uphold his beliefs,{{Sfn|Veccia Vaglieri|2012a}}{{Sfn|Steigerwald|2004}} but was also magnanimous in victory,{{sfn|Madelung|1997|pp=309–310}}{{sfn|Momen|1985|p=25}} even risking the ire of some supporters to prevent the enslavement of women.{{sfn|Veccia Vaglieri|2012a}} He also showed his grief, wept for the dead, and reportedly prayed over his enemies.{{sfn|Veccia Vaglieri|2012a}} Yet Ali has also been criticized for his idealism and political inflexibility,{{Sfn|Veccia Vaglieri|2012a}}{{Sfn|Madelung|1997|p=|pp=149–50}} for his egalitarian policies and strict justice antagonized many.{{Sfn|Ayoub|2014|p=134}}{{Sfn|Tabatabai|1975|p=44}} Or perhaps these qualities were also present in Muhammad,{{Sfn|Tabatabai|1975|p=46}}{{Sfn|Shah-Kazemi|2019|p=89}} whom the Quran addresses as, "They wish that thou [Muhammad] might compromise and that they might compromise."{{Sfn|Tabatabai|1975|p=|pp=46, 64}} At any rate, these qualities of Ali, rooted in his religious beliefs, contributed to his image today for his followers as a paragon of Islamic virtues,{{sfn|Veccia Vaglieri|2012a}}{{Sfn|Madelung|1997|p=310}}{{Sfn|Ayoub|2014|p=134}} particularly justice.{{sfn|Shah-Kazemi|2015b}} Ali is also viewed as the model {{Transliteration|el|par excellence}} for Islamic chivalry ({{Transliteration|ar|[[futuwwa]]}}).{{Sfn|Shah-Kazemi|2007|p=189n1}}{{Sfn|Glassé|2001|p=41}}{{Sfn|Momen|1985|p=90}}

Historical accounts about Ali are often tendentious.{{sfn|Veccia Vaglieri|2012a}} For instance, in person, Ali is described in some Sunni sources as bald, heavy-built, short-legged, with broad shoulders, hairy body, long white beard, and affected by eye inflammation.{{Sfn|Veccia Vaglieri|2012a}} Shia accounts about the appearance of Ali are markedly different. Those perhaps better match his reputation as a capable warrior.{{sfn|Abbas|2021|p=63}} Likewise, in manner, Ali is presented in some Sunni sources as rough, brusque, and unsociable.{{sfn|Veccia Vaglieri|2012a}} By contrast, Shia sources describe him as generous, gentle, and cheerful,{{sfn|Glassé|2001|p=41}}{{sfn|Shah-Kazemi|2015b}} to the point that the Syrian war propaganda accused him of frivolity.{{Sfn|Shah-Kazemi|2019|p=105}} Shia and [[Sufism|Sufi]] sources are also replete with reports about his acts of kindness, especially to the poor.{{Sfn|Shah-Kazemi|2019|p=|pp=35{{ndash}}36}} The necessary qualities in a commander, described in a letter attributed to Ali, may have well been a portrait of himself: slow to anger, happy to pardon, kind to the weak, and severe with the strong.{{Sfn|Shah-Kazemi|2019|p=104}} His companion, [[Sa'sa'a bin Sohan|Sa'sa'a ibn Suhan]], described him similarly, "He [Ali] was amongst us as one of us, of gentle disposition, intense humility, leading with a light touch, even though we were in awe of him with the kind of awe that a bound prisoner has before one who holds a sword over his head."{{sfn|Shah-Kazemi|2015b}}{{sfn|Shah-Kazemi|2019|p=104}}

=== In Islam ===
Ali's place is said to be second only to Muhammad in [[Islamic culture|Muslim culture]].{{sfn|Poonawala|1982}} Ali is revered for his courage, honesty, unbending devotion to Islam, magnanimity, and equal treatment of all Muslims.{{sfn|Madelung|1997|pp=309–310}} For his admirers, he has thus become the archetype of uncorrupted Islam and pre-Islamic chivalry.{{sfn|Madelung|1997|p=310}}

==== In the Quran ====
Ali regularly represented Muhammad in missions which are commonly linked to Quranic injunctions.{{sfn|Lalani|2006}}{{sfn|Momen|1985|pp=11–12}} For instance, the [[Verse of walaya|verse of {{Transliteration|ar|walaya}}]] (5:55) is a reference to when Ali gave his ring to a beggar, while praying in the mosque, according to Shia and some Sunni accounts.{{sfn|Nasr|Dagli|Dakake|Lumbard|2015|p=706}} If so, then this verse gives Ali the same spiritual authority ({{Transliteration|ar|[[walaya]]}}) as Muhammad.{{sfn|Nasr|Dagli|Dakake|Lumbard|2015|p=706-7}}{{Sfn|Mavani|2013|p=46}} In Shia sources, the {{Transliteration|ar|[[verse of tabligh]]}} (5:67) spurred Muhammad to designate Ali as his successor at the Ghadir Khumm, while the {{Transliteration|ar|[[verse of ikmal al-din]]}} (5:3) subsequently announced the perfection of Islam.{{Sfn|Mavani|2013|pp=70{{ndash}}71}} The [[verse of purification]] (33:33) concerns the status of purity of the [[Ahl al-Bayt]] ({{Lit|people of the house}}), which is limited to Ali, Fatima, and their two sons in Shia and some Sunni sources.{{Sfn|Momen|1985|pp=16, 17}}{{Sfn|Leaman|2006}}{{Sfn|Momen|1985|pp=16–7, 325}} Another reference to the Ahl al-Bayt might be the [[Verse of mawadda|verse of {{Transliteration|ar|mawadda}}]] (42:23).{{sfn|Lalani|2000|p=66}}{{Sfn|Momen|1985|p=152}}{{Sfn|Mavani|2013|p=|pp=41, 60}} For Shias, this verse is a Quranic mandate to love and follow the Ahl al-Bayt.{{Sfn|Mavani|2013|p=41|pp=}}{{sfn|Lalani|2000|pp=|p=66}}

==== In hadith literature ====
Muhammad frequently praise the qualities of Ali. The most controversial such statement, "He whose {{Transliteration|ar|mawla}} I am, Ali is his {{Transliteration|ar|mawla}}," was delivered at the Ghadir Khumm. This gave Ali the same spiritual authority ({{Transliteration|ar|walaya}}) as Muhammad, according to the Shia.{{Sfn|Tabatabai|1975|p=35}} Elsewhere, the [[hadith of the position]] likens Muhammad and Ali to Moses and Aaron,{{sfn|Miskinzoda|2015|p=69}} and thus supports the usurped right of Ali to succeed Muhammad in Shia Islam.{{Sfn|Miskinzoda|2015|p=76}} Other examples in standard Shia and Sunni collections of hadith include, "There is no youth braver than Ali," "No-one but a believer loves Ali, and no-one but a hypocrite ([[Munafiq|{{transliteration|ar|munafiq}}]]) hates Ali," "I am from Ali, and Ali is from me, and he is the {{Transliteration|ar|wali}} ({{Literal translation|patron|guardian}}) of every believer after me," "The truth revolves around him [Ali] wherever he goes," "I am the city of knowledge and Ali is its gate ([[Bab (Shia Islam)|{{transliteration|ar|bab}}]])," "Ali is with the Quran and the Quran is with Ali. They will not separate until they return to me at the [paradisal] pool."{{sfn|Momen|1985|pp=14{{ndash}}15}}{{sfn|Shah-Kazemi|2014}}

==== In Sufism ====
Ali is the common source of mystical and spiritual currents within both Sunni and Shia sects of Islam.{{Sfn|Shah-Kazemi|2007|p=134}}{{Sfn|Louër|2020|p=30}} In particular, Ali is the spiritual head of some Sufi movements,{{sfn|Gleave|2008}} for Sufis believe that Ali inherited from Muhammad his esoteric knowledge and saintly authority,{{sfn|Afsaruddin|Nasr|2023}} which guide believers on their journey toward God.{{sfn|Gleave|2008}} Nearly all Sufi orders trace their lineage to Muhammad through Ali, an exception being the [[Naqshbandi]]s, who reach Muhammad through Abu Bakr.{{sfn|Afsaruddin|Nasr|2023}}

==== In Sunni Islam ====

In Sunni Islam, Ali is venerated as a close companion of Muhammad,{{Sfn|Rauf|2007|p=201}} a foremost authority on the Quran and Islamic law,{{Sfn|Lalani|2006|p=28}}{{Sfn|Rauf|2007|p=202}} and the fountainhead of wisdom in Sunni spirituality.{{Sfn|Shah-Kazemi|2007|p=134}} When the prophet died in 632, Ali had his claims to leadership, perhaps in reference to the Ghadir Khumm,{{Sfn|Momen|1985|pp=19{{ndash}}20}}{{Sfn|Amir-Moezzi|2014}} but he eventually accepted the temporal rule of the first three caliphs in the interest of Muslim unity.{{Sfn|Keaney|2021|p=136}} Ali is portrayed in Sunni sources as a trusted advisor of the first three caliphs,{{sfn|Afsaruddin|Nasr|2023}}{{sfn|Poonawala|1982}} while their conflicts with Ali are minimized,{{Sfn|Jafri|1979|p=45}}{{Sfn|Shah-Kazemi|2019|p=78}} in line with the Sunni tendency to show accord among companions.{{Sfn|Shah-Kazemi|2019|p=78}}{{Sfn|Lucas|2004|p=255-84}}{{Sfn|Soufi|1997|p=120}} As the fourth and final Rashidun caliph, Ali holds a particularly high status in Sunni Islam, although this doctrinal reverence for Ali is a recent development for which the prominent Sunni traditionist [[Ahmad ibn Hanbal|Ibn Hanbal]] ({{Died in|855}}) is likely to be credited.{{Sfn|Gleave|2008}} Sunni hierarchy of companions places Ali below his three predecessors and above those who fought against him.{{Sfn|Gleave|2008}}{{Sfn|Crone|2005|p=135}}{{Sfn|Rauf|2007|p=201}} This ordering has required Sunni reinterpretation of those prophetic sayings that explicitly elevate Ali above all companions.{{Sfn|Gleave|2008}}

==== In Shia Islam ====
Ali takes center stage in Shia Islam:{{Sfn|Afsaruddin|Nasr|2023}} The Arabic word ''shi'a'' itself is short for '{{Transliteration|ar|shi'a}} of Ali' ({{Lit|followers of Ali}}),{{Sfn|Shomali|2003|p=14}} his name is incorporated into the daily call to prayer ({{Transliteration|ar|[[adhan]]}}),{{Sfn|Afsaruddin|Nasr|2023}} and he is regarded as the foremost companion of Muhammad.{{Sfn|Steigerwald|2004|p=36}}{{Sfn|Poonawala|2014|p=305}} The defining doctrine of Shia Islam is that Ali was the rightful successor of Muhammad through divinely-ordained designation,{{Sfn|Poonawala|1982}}{{Sfn|Momen|1985|p=147}} which is primarily a reference to the Ghadir Khumm.{{Sfn|Daftary|2015|p=172}} Ali is thought to have inherited the political and religious authority of Muhammad, even before his ascension to the caliphate in 656.{{sfn|Gleave|2004}}{{sfn|Mavani|2013|pp=52, 53}} In particular, Ali's predecessors are regarded as illegitimate rulers and usurpers of his rights.{{Sfn|Poonawala|1982}} The all-encompassing bond of loyalty between Shia Muslims and their imams (and Muhammad in his capacity as imam) is known as {{Transliteration|ar|walaya}}.{{Sfn|Haider|2014|p=34}} Ali is also thought to be endowed with the privilege of [[Shafa'a|intercession]] on the [[Judgement Day in Islam|Judgment Day]].{{sfn|Gleave|2008}} Early on, some Shias even attributed divinity to Ali,{{Sfn|Poonawala|1982}}{{Sfn|Steigerwald|2004|p=36}} but such extreme views were gradually rooted out of Shi'ism.{{Sfn|Momen|1985|pp=67{{ndash}}68}}

In Shia belief, Ali also inherited the esoteric knowledge of Muhammad,{{Sfn|Shah-Kazemi|2015b}}{{Sfn|Steigerwald|2004|p=37}} for instance, in view of the prophetic hadith, "I [Muhammad] am the city of knowledge, and Ali is its gate."{{Sfn|Shah-Kazemi|2015b}} Ali is thus regarded, after Muhammad, as the interpreter, {{Transliteration|el|par excellence}}, of the Quran and the sole authoritative source of its (esoteric) teachings.{{Sfn|Daftary|2015|p=172}} Unlike Muhammad, however, Ali is not thought to have received [[Wahy|divine revelation]] ({{Transliteration|ar|wahy}}), though he might have been guided by divine inspiration ({{Transliteration|ar|ilham}}).{{sfn|Gleave|2004}}{{sfn|Mavani|2013|pp=52{{ndash}}53}} Verse 21:73 of the Quran is sometimes cited here, "We made them imams, guiding by Our command, and We revealed ({{Transliteration|ar|awhayna'}}) to them the performance of good deeds, the maintenance of prayers, and the giving of [[Zakat|{{transliteration|ar|zakat}}]] (alms), and they used to worship Us."{{sfn|Tabatabai|1975|pp=186–189}} Shia Muslims also believe in the [[Ismah|infallibility]] of Ali, as with Muhammad, that is, their divine protection from sins.{{sfn|Gleave|2008}}{{Sfn|Haider|2014|p=42}} Here, the [[verse of purification]] is sometimes cited.{{sfn|Mavani|2013|p=68}}{{Sfn|Momen|1985|p=155}} Ali's [[Sunnah|words and deeds]] are therefore considered a model for the Shia community and a source for their religious injunctions.{{sfn|Momen|1985|p=174}}{{sfn|Shah-Kazemi|2015a|p=38}}

==== In Alawism ====
The [[Alawites]] venerate Ali, the first of the Twelve Imams, as the physical manifestation of God.{{Sfn|Nisan|2002|p=116}}{{Sfn|Cosman|Jones|2009|p=407}} Even, the Alawite testimony of faith (''[[shahada]]'') translates as "there is no God but Ali".{{Sfn|Atwan|2015|p=58}} The Alawite trinity envisions God as being composed of three distinct manifestations, ''Ma'na'' (meaning), ''Ism'' (Name) and ''Bab'' (Door); which together constitute an "indivisible trinity". ''Ma'na'' symbolises the "source and meaning of all things" in Alawite mythology. According to Alawite doctrines, ''Ma'na'' generated the ''Ism'', which in turn built the ''Bab''. These beliefs are closely tied to the Alawite doctrine of reincarnations of the trinity.{{Sfn|Ismail|2016|p=67}}{{Sfn|Moosa|1987|p=311–312}} The final trinity of [[reincarnation]] in the Alawite trinity consists of Ali (''Ma'na''), Muhammad (''Ism'') and [[Salman the Persian]] (''Bab''). Alewites depict them as the sky, sun and moon respectively. Alawites deify Ali as the "last and supreme manifestation of God" who built the universe, attribute to him divine superiority, and believe that Ali created Muhammad and gave him the mission to spread Qur'anic teachings on earth.{{Sfn|Moosa|1987|p=312}}{{Sfn|Esposito|Moosa|1995|p=64}}{{Sfn|Ismail|2016|p=67}}{{Sfn|Nisan|2002|p=115, 117}}

=== In other religions ===
In the [[Druze]] faith, Ali is considered a "minor prophet," like [[Plato]] and [[Socrates]].<ref>[https://rpl.hds.harvard.edu/faq/druze-syria "Druze in Syria"]. ''Harvard Divinity School''. [[Harvard University Press]]. Archived from [https://web.archive.org/web/20230920161333/https://rpl.hds.harvard.edu/faq/druze-syria the original] on 9 December 2023. Retrieved 9 December 2023.</ref> Even though the faith originally developed out of the [[Isma'ilism|Isma'ili]] branch of Shia Islam, the Druze are not Muslims,{{Sfn|Jacobs|2014|p=193}}{{Sfn|McLaurin|1979|p=114}} and do not accept the [[Five Pillars of Islam|five pillars of Islam]].{{Sfn|McLaurin|1979|p=114}} In [[Yarsanism]], a religion founded by the [[Kurdish population|Kurdish]] mystic [[Sultan Sahak]], Ali is thought to be an incarnation of God,{{Sfn|Algar|1994|p=513}} and superior to Muhammad,{{Sfn|Algar|1994|p=513}} but their image as a [[Ghulat]] ({{Lit|exaggerators|extremists}}) subsect of Shia Islam is incorrect''.''{{Sfn|Algar|1994|p=513}}

==Historiography==
{{See also|Historiography of early Islam}}

Much has been written about Ali in Islamic literature, second only to Muhammad.{{sfn|Afsaruddin|Nasr|2023}} However, much of this material is colored by a positive or negative bias towards Ali.{{sfn|Afsaruddin|Nasr|2023}} The [[primary sources]] about Ali are the Quran, hadiths, and other [[Historiography of early Islam|early Islamic works]],{{sfn|Afsaruddin|Nasr|2023}} the most notable being ''[[The Book of Sulaym ibn Qays]]'', attributed to a companion of Ali.{{sfn|Clarke|2005|p=59}} Such works were initially scarce, but this changed with the introduction of affordable paper in the Abbasid period. For instance, at least twenty-one monographs were composed on the Battle of Siffin between 750 and 950, thirteen of which were authored by the early historian [[Abu Mikhnaf]] ({{Died in|773{{ndash}}774}}). Most of these monographs are not extant except through quotations in later collections, such as the tenth-century {{Transliteration|ar|[[Tarikh al-Tabari]]}}.{{sfn|Robinson|2003|pp=27, 28, 34}} In addition to numerous works authored by Muslims, the [[secondary source]]s about Ali include writings of [[Christian Arabs|Arab Christians]], [[Hindus]], and also works by Western scholars.{{sfn|Afsaruddin|Nasr|2023}} When writing about Ali, early Western scholars often dismissed as fabricated the reports gathered in later periods because their authors often advanced their own Sunni or Shia partisan views. For instance, [[Leone Caetani|L. Caetani]] ({{Died in|1935}}) often rejected the historical reports attributed to the pro-Ali Ibn Abbas and anti-Ali Aisha. Caetani instead preferred accounts reported without [[isnad|{{transliteration|ar|isnad}}]] by early historians like [[Ibn Ishaq]] ({{Died in|767}}). By contrast, [[Wilferd Madelung|W. Madelung]] ({{Died in|2023}}) argued that the tendentiousness of a report alone does not imply its fabrication. Madelung instead advocated for the authentication of historical reports on the basis of their compatibility with other events and figures.{{sfn|Madelung|1997|pp=xi, 19, 20}}
