ʿAli ibn Abi Talib (c. 600–661) was the cousin and son-in-law of the Prophet Muhammad ﷺ, husband of Fatima al-Zahra, father of Hasan and Husayn, an early Muslim and prominent companion, and the fourth caliph from 656 to 661. His life joins the formative history of Islam to the first Muslim civil war and later became central to both Sunni memory and Shi‘i doctrines of the imamate.

ʿAli ibn Abi Talib
ʿAli ibn Abi Talib (c. 600–661) stood at the center of several generations of Islamic memory at once. He was a first cousin of the Prophet Muhammad ﷺ, grew up close to his household, married his daughter Fatima, and became the father of Hasan and Husayn. He appears throughout the record of the Medinan community as a fighter, envoy, scribe, family member and transmitter of legal knowledge. After the assassination of ʿUthman ibn ʿAffan in 656, ʿAli became caliph during a political crisis that developed into the first Muslim civil war. His caliphate was therefore both a government and a prolonged struggle over authority, accountability for ʿUthman’s killing and the political future of the community. Later Sunni and Shi‘i traditions both placed extraordinary importance on him, though they interpreted his place in succession and religious authority in different ways.

Origins and Banu Hashim
ʿAli was the son of Abu Talib ibn ʿAbd al-Muttalib and Fatima bint Asad, and thus belonged to Banu Hashim, the same Qurashi clan as the Prophet Muhammad ﷺ. Abu Talib was the Prophet’s ﷺ paternal uncle and had protected him during the difficult Meccan years despite not joining the new faith according to the dominant Muslim account. Through this family connection, ʿAli was not simply a later companion who entered the Prophet’s ﷺ circle as an adult: he belonged to the household environment in which the earliest phase of the mission unfolded. Sources commonly place his birth around 600 CE, but the exact year is uncertain.
Sources: [1] Reference biography
Growing up in the Prophet’s ﷺ household
Early Muslim biography relates that economic hardship affected Abu Talib’s large household and that the Prophet Muhammad ﷺ took the young ʿAli into his care. This placed ʿAli in the Prophet’s ﷺ home before the public expansion of Islam. The tradition is important for understanding why later reports remember him as exceptionally close to the first revelations and to the private life of the household. It also helps explain the unusual combination of kinship and discipleship that marked his later relationship with the Prophet ﷺ.

One of the earliest Muslims
Muslim biographical traditions consistently place ʿAli among the earliest people to accept Islam, while he was still young. Sources differ in how they rank the first converts because they divide the early community into categories such as adult men, women, youths and freed persons. What is stable across the tradition is that ʿAli’s adherence belongs to the earliest Meccan phase, not to a later period when Islam had already become politically secure. His youth also meant that much of his formation occurred inside the new religious community itself.
Sources: [1] Reference biography, [2] Ibn Ishaq/Ibn Hisham sira, English translation
The Meccan years
During the Meccan period ʿAli remained closely associated with the Prophet Muhammad ﷺ and Banu Hashim as pressure on the early Muslims increased. Sira literature places him within the network of relatives and believers who supported the Prophet ﷺ through boycott, social pressure and the years preceding the Hijra. A famous early-biographical narrative also associates him with the night of the Prophet’s ﷺ departure from Mecca, when ʿAli is said to have slept in his bed and remained behind temporarily to return property entrusted to the Prophet ﷺ. The basic association of ʿAli with the Hijra transition is old; individual details of the bed narrative are transmitted through biographical rather than the strongest hadith collections.
Sources: [2] Ibn Ishaq/Ibn Hisham sira, English translation
Hijra and a new life in Medina
After the Prophet Muhammad ﷺ left Mecca, ʿAli followed to Medina. The migration transformed his role. In Mecca he had been a young member of a persecuted household; in Medina he entered adult family life and participated in the community’s military, legal and political affairs. His proximity to the Prophet ﷺ continued, but now alongside a much larger body of Emigrants and Ansar. The Medinan record preserves ʿAli in very different settings: on the battlefield, writing agreements, carrying out missions, discussing law and sharing the ordinary concerns of a young household.

Marriage to Fatima al-Zahra
ʿAli married Fatima, daughter of the Prophet Muhammad ﷺ, in Medina. Sahih al-Bukhari preserves an unusually concrete glimpse of the material circumstances surrounding the marriage. ʿAli had two she-camels and planned to gather and sell idhkhir grass to help pay for his wedding banquet. Before he could do so, Hamza—who had been drinking before the prohibition of wine was completed—slashed the camels’ humps and sides. ʿAli went to the Prophet ﷺ in distress, and the report describes the Prophet ﷺ confronting Hamza before withdrawing when he saw Hamza’s intoxicated state. The story is memorable precisely because it presents the household not as an abstract genealogy but as young people dealing with money, preparations, relatives and an unexpected disaster.
Sources: [1] Reference biography, [9] Sahih al-Bukhari 4003
Family life, Hasan and Husayn
The marriage of ʿAli and Fatima produced, among other children, Hasan and Husayn, whose descendants became central to later Islamic history. Hadith also preserves intimate scenes from the home. In one report, the Prophet Muhammad ﷺ visited ʿAli and Fatima at night and asked why they were not praying; ʿAli answered that their souls were in Allah’s hand and that He would wake them if He willed. The Prophet ﷺ left while reciting the Qur’anic observation that the human being is exceptionally argumentative. Another affectionate household story explains the nickname Abu Turab: after ʿAli had lain down in the mosque and dust covered his back, the Prophet ﷺ brushed the dust from him and called him “Abu Turab.” The name became one ʿAli himself was remembered as liking.

Badr
ʿAli participated in the Battle of Badr in 624, the first major armed confrontation between the Medinan Muslims and Quraysh. Reports place him among the fighters in the opening combat and the battle more generally. Sahih al-Bukhari also records a practical consequence of Badr in ʿAli’s own words: he received a she-camel from his share of the booty and another from the Prophet Muhammad ﷺ, assets he later hoped to use in preparing for his marriage to Fatima. The detail connects the famous battle to the economic life of a young member of the community.
Sources: [1] Reference biography, [9] Sahih al-Bukhari 4003
Uhud and tending the Prophet’s ﷺ wounds
At Uhud in 625 the Muslim army suffered severe reversals and the Prophet Muhammad ﷺ was wounded. Sahih al-Bukhari preserves a domestic-medical scene after the fighting: Fatima washed her father’s wounds while ʿAli poured water from a shield. When the water increased the bleeding, Fatima burned a piece of mat and applied its ash to stop it. The account shows ʿAli not only as a combatant in the military narratives but as part of the family circle caring for the Prophet ﷺ in the immediate aftermath.
Sources: [1] Reference biography, [10] Sahih al-Bukhari 4075
The scribe at Hudaybiyyah
At Hudaybiyyah in 628, ʿAli served as the scribe for the agreement between the Prophet Muhammad ﷺ and the Meccans. Sahih al-Bukhari reports that when the document described Muhammad ﷺ as the Messenger of Allah, the Meccan negotiators objected to that title. The Prophet ﷺ asked ʿAli to erase the words; ʿAli replied that he would not erase the designation. The Prophet ﷺ then had the place shown to him and removed it. The episode is a striking example of the tension between devotion and negotiation: ʿAli’s reluctance did not prevent the treaty from being concluded, and the treaty itself became a turning point in the community’s political position.
Sources: [1] Reference biography, [4] Sahih al-Bukhari 2699
The flag at Khaybar
The Khaybar campaign in 628–629 produced one of the best-known hadiths concerning ʿAli. Sahih al-Bukhari reports that the Prophet Muhammad ﷺ announced that he would give the flag to a man who loved Allah and His Messenger ﷺ and was loved by Allah and His Messenger ﷺ. The next morning he called for ʿAli, who was suffering from an eye ailment. The Prophet ﷺ treated his eye, prayed for him and gave him the flag. He then instructed ʿAli to approach calmly, invite the opposing people to Islam and explain their obligations, adding that guiding one person would be better than possessing prized red camels. The report combines martial leadership with an instruction not to rush immediately into combat.
Sources: [1] Reference biography, [7] Sahih al-Bukhari 3701
Toward the conquest of Mecca
ʿAli remained an active member of the Prophet Muhammad ﷺ’s circle during the campaigns and diplomacy that led to the conquest of Mecca in 630. He had already acted as scribe at Hudaybiyyah and later took part in a sensitive mission connected with the secrecy of the Meccan campaign. His position by this point was not defined by a single office: he could be used as a fighter, messenger, investigator or representative depending on the situation. This flexibility appears repeatedly in the Medinan record.
Sources: [1] Reference biography, [12] Sahih al-Bukhari 4274
The intercepted letter of Hatib
Shortly before the conquest of Mecca, the Prophet Muhammad ﷺ learned that Hatib ibn Abi Baltaʿa had sent a letter revealing information to people in Mecca. Sahih al-Bukhari reports that he dispatched ʿAli, al-Zubayr and al-Miqdad to intercept the courier at Rawdat Khakh. They recovered the concealed letter and brought it back. Hatib then explained that he had acted to protect relatives in Mecca rather than from disbelief, and the Prophet ﷺ accepted his explanation. The episode shows ʿAli entrusted with a mission involving intelligence, speed and the handling of a politically dangerous accusation.
Sources: [1] Prophetic-period service, [12] Sahih al-Bukhari 4274
Yemen, authority and a complaint
The Prophet Muhammad ﷺ also sent ʿAli on missions to Yemen. One cluster of reports concerns ʿAli’s administration of property from the khums and complaints made about his decisions. Sahih al-Bukhari preserves Buraida’s admission that he disliked ʿAli and complained to the Prophet ﷺ after a Yemen mission; the Prophet ﷺ rejected the hostility and affirmed ʿAli’s entitlement in the matter at issue. Other traditions remember ʿAli acting in judicial or representative capacities in Yemen. These missions helped give him experience beyond Medina before the Prophet’s ﷺ death.
Sources: [1] Reference biography, [13] Sahih al-Bukhari 4350
Tabuk and the Aaron–Moses saying
When the Prophet Muhammad ﷺ departed for Tabuk in 630, he left ʿAli in Medina. ʿAli was dissatisfied at being left with the non-combatants. Sahih al-Bukhari records the Prophet ﷺ reassuring him: “Are you not pleased that you are to me as Aaron was to Moses, except that there is no prophet after me?” The wording is strongly attested and became one of the most discussed statements about ʿAli’s relationship to the Prophet ﷺ. In its immediate narrative setting it accompanies ʿAli’s temporary responsibility in Medina during the expedition.
Sources: [14] Sahih al-Bukhari 4416
The final years of the Prophet ﷺ
In the final Medinan years, ʿAli remained a close relative, companion and operative of the Prophet Muhammad ﷺ. He appears in reports about missions, property, agreements and family affairs rather than as holder of a single permanent bureaucratic title. When the Prophet ﷺ became seriously ill, Sahih al-Bukhari identifies ʿAli as one of the men supporting him as he walked between his rooms. The later political importance of ʿAli can make it easy to read every earlier episode only as a prelude to succession; the surviving record is broader, showing years of kinship, service, disagreement, affection and responsibility.
Sources: [1] Reference biography
Ghadir Khumm
On the return journey from the Farewell Pilgrimage, Islamic tradition records a gathering at Ghadir Khumm in which the Prophet Muhammad ﷺ spoke concerning ʿAli. Jami at-Tirmidhi transmits the concise wording: “For whomever I am his mawla, ʿAli is his mawla,” a report graded sahih in the edition represented in the hadith database. The statement itself became enormously important in later Muslim thought. Sunni interpreters commonly emphasize loyalty, love, support or ʿAli’s standing, while Shi‘i interpretation understands the declaration as part of the Prophet’s ﷺ designation of ʿAli to authoritative leadership. The historical report and the later interpretations therefore need to be distinguished without pretending that the interpretive disagreement does not exist.

The Prophet’s ﷺ death and the question of succession
The death of the Prophet Muhammad ﷺ in 632 created an immediate political problem for which the community had no single uncontested procedure. While members of the Prophet’s ﷺ family were occupied with the aftermath of his death, a meeting at Saqifa led to Abu Bakr becoming caliph. ʿAli did not participate in the initial Saqifa deliberation. Early and later sources preserve different understandings of what authority ʿAli believed was due to the Prophet’s ﷺ family and how this related to earlier statements such as those at Ghadir Khumm and Tabuk. The basic chronology of Abu Bakr’s accession is clear; the religious meaning and legitimacy assigned to it became one of the central Sunni–Shi‘i disagreements.
Sources: [1] Reference biography, [16] Chapter 4, pp. 141–310
Fatima, Fadak and reconciliation with Abu Bakr
Sahih al-Bukhari preserves a difficult episode after the Prophet Muhammad ﷺ’s death. Fatima sought property associated with Fadak, Khaybar and Medina, while Abu Bakr cited the Prophet ﷺ as saying that prophetic property was not inherited in the ordinary manner and was left as charity. The report says that Fatima remained displeased and died about six months after her father. It also records that ʿAli had not yet given Abu Bakr a public oath of allegiance during those months and later sought reconciliation and pledged to him. These reports are among the most important early materials for the relationship between the Prophet’s ﷺ household and the first caliphate, and later Sunni and Shi‘i traditions place very different emphases on them.
Sources: [11] Sahih al-Bukhari 4240–4241, [16] Chapter 4, pp. 141–310
During the caliphate of ʿUmar
Under ʿUmar ibn al-Khattab, ʿAli remained an important member of the Medinan elite and appears in legal consultation and communal affairs. The sources do not present him as politically erased: he participated in consultation and retained his standing as a member of the Prophet Muhammad ﷺ’s family and an early companion. Sahih al-Bukhari also preserves ʿAli speaking warmly after ʿUmar’s death, recalling how frequently he had heard the Prophet ﷺ say “I, Abu Bakr and ʿUmar” in connection with shared actions. At the same time, later debates over succession caused the relationship among the early caliphs to be remembered differently in competing theological traditions.

During the caliphate of ʿUthman
ʿAli remained in Medina during ʿUthman ibn ʿAffan’s caliphate and was drawn increasingly into the tensions of its later years. Sources portray him at various moments advising, criticizing or mediating rather than simply belonging to a fixed anti-ʿUthman faction. As opposition to the caliph intensified, accusations about governors, distribution of patronage and provincial administration converged with wider political rivalries. After the rebels besieged and killed ʿUthman in 656, the question of who could restore order became inseparable from the unresolved demand to identify and punish those responsible.
Sources: [1] Reference biography, [16] Chapter 4, pp. 141–310
Accession in 656
After ʿUthman’s killing, ʿAli accepted the caliphate in Medina amid severe instability. His accession did not begin from a settled consensus comparable to an orderly transfer of office. Some leading Muslims pledged to him, others withheld support or demanded that the killers of ʿUthman be prosecuted before political normality could be restored, and Syria under Muʿawiya ibn Abi Sufyan did not recognize his authority. ʿAli’s government therefore faced a circular problem: effective prosecution required political control, while opponents argued that political legitimacy required immediate prosecution. The conflict soon moved from negotiation to civil war.
Sources: [1] Reference biography, [16] Chapter 4, pp. 141–310
The Battle of the Camel
In late 656, Aisha, Talha ibn ʿUbayd Allah and al-Zubayr ibn al-ʿAwwam became associated with a movement demanding accountability for the murder of ʿUthman. Their forces and ʿAli’s met near Basra. Accounts preserve negotiations as well as fighting, but the surviving narratives differ over precisely how hostilities began and which actors made reconciliation impossible. The battle ended in ʿAli’s victory; Talha and al-Zubayr died, and Aisha was treated with respect and returned to Medina. Because later political and sectarian memory strongly shaped portrayals of all the principal participants, assigning a simple moral script to the outbreak goes beyond what the conflicting sources securely establish.
Sources: [1] Reference biography, [16] Chapter 4, pp. 141–310
Kufa as the center of government
After the Basran campaign, ʿAli shifted the political center of his caliphate to Kufa. The move reflected the strategic weight of Iraq: its garrison cities supplied soldiers, revenue and access to the eastern provinces. Kufa also placed ʿAli closer to the military confrontation with Syria. Governing from Iraq, however, brought its own pressures. The coalition supporting him contained tribal leaders, early settlers, pious activists and men with different expectations of war and patronage. Much of the difficulty of his caliphate came from having to maintain authority over allies who did not always agree with one another.
Sources: [1] Reference biography, [16] Chapter 4, pp. 141–310
Siffin
The principal military confrontation between ʿAli and Muʿawiya occurred at Siffin on the Euphrates in 657. Muʿawiya, governor of Syria and a relative of ʿUthman, demanded accountability for the slain caliph and refused to recognize ʿAli’s authority under the prevailing conditions. The armies fought over an extended period. As the conflict reached a critical point, the Syrian side called for recourse to the Qur’an and negotiations. ʿAli accepted arbitration under pressure from elements within his own coalition, although accounts differ over the balance between his own preference, battlefield circumstances and demands from his followers. The decision halted that phase of fighting but did not resolve the political contest.
Sources: [1] Reference biography, [16] Chapter 4, pp. 141–310
The arbitration crisis
Representatives were appointed to arbitrate after Siffin, commonly identified as Abu Musa al-Ashʿari for ʿAli’s side and ʿAmr ibn al-ʿAs for Muʿawiya’s. The arbitration weakened rather than stabilized ʿAli’s coalition. Some of those who had pressed for accepting human arbitration then condemned the very process, using the slogan that judgment belongs to Allah alone. Later narrative sources contain vivid stories about the arbitrators publicly deposing leaders and one outmaneuvering the other; the chronology and reliability of these dramatic scenes vary across the sources. What is historically clear is that arbitration failed to reunify the community and contributed to further fragmentation.
Sources: [1] Reference biography, [16] Chapter 4, pp. 141–310
The Kharijites and Nahrawan
The group that broke with ʿAli after Siffin and arbitration became associated with the early Kharijites. Their conflict with his government escalated beyond doctrinal protest into violence. ʿAli eventually fought them at Nahrawan in 658. This episode has unusually strong hadith connections: Sahih al-Bukhari and Sahih Muslim preserve reports describing a group that would emerge during internal dissension and identifying a distinctive man among them; reports state that ʿAli’s forces searched the battlefield and found the described figure after the fighting. Even after Nahrawan, Kharijite opposition did not disappear and remained part of the violent political environment of ʿAli’s final years.
Sources: [1] Reference biography, [5] Sahih al-Bukhari 3610, [16] Chapter 4, pp. 141–310
Knowledge, law and transmitted teaching
ʿAli became one of the major authorities cited in later Islamic legal, ethical and devotional literature. Sahih al-Bukhari preserves him referring to a written sheet containing rulings concerning blood money, wounds, the sanctuary of Medina and guarantees of protection, while explicitly denying possession of a hidden scriptural book apart from the Qur’an. Numerous legal reports are transmitted from him across the hadith collections. Later Sunni legal schools and Shi‘i jurisprudence both drew on material attributed to ʿAli, though the corpora and methods by which they authenticated that material differ considerably. Famous collections of speeches and sayings attributed to him likewise contain material of varying transmission history and must be assessed item by item.
Sources: [1] Later learning and memory, [17] Sahih al-Bukhari 3172
Character and remembered everyday scenes
The strongest sources preserve ʿAli in scenes that resist a one-dimensional heroic portrait. He could show intense devotion, but Sahih al-Bukhari also remembers his witty or argumentative answer when the Prophet Muhammad ﷺ woke him and Fatima for night prayer. He was renowned for courage, yet the marriage-camel story shows him weeping in frustration and going to the Prophet ﷺ for help. The Abu Turab episode preserves affection and humor. At Hudaybiyyah his devotion made him reluctant to erase the Prophet’s ﷺ title even though the negotiation required it. Another report has ʿAli telling his son Muhammad ibn al-Hanafiyya that Abu Bakr and then ʿUmar were the best people after the Prophet ﷺ, while describing himself modestly as an ordinary Muslim. These varied reports are valuable because they show personality through actions rather than later slogans.

Assassination in Kufa
In 661, while the civil conflict remained unresolved, ʿAli was attacked in Kufa by ʿAbd al-Rahman ibn Muljam, a man associated in the historical tradition with the Kharijite milieu. ʿAli died from the wound. His death ended a caliphate of roughly five years marked by almost continuous internal conflict and left Muʿawiya in the strongest political position. Early traditions also reflect concern that ʿAli’s grave should not become a target during a period of intense hostility, and accounts of the precise burial place developed in different forms. Najaf later became overwhelmingly identified in Shi‘i tradition as the location of his tomb.
Sources: [1] Reference biography, [16] Chapter 4, pp. 141–310
Legacy across Muslim traditions
Few figures after the Prophet Muhammad ﷺ have carried as many overlapping meanings as ʿAli. Sunni tradition remembers him as a pre-eminent companion, member of the Prophet’s ﷺ household, learned authority and the fourth of the Rightly Guided Caliphs. Shi‘i traditions place him at the beginning of the line of Imams and regard his authority after the Prophet ﷺ as divinely grounded, with Ghadir Khumm among the central proofs. Sufi lineages frequently trace spiritual transmission through him, and Arabic ethical and literary culture preserves a vast corpus of sayings attached to his name. Historical study must therefore distinguish the seventh-century individual from the many later communities that made him a model of courage, justice, knowledge, piety, legitimate authority or martyrdom. Those later memories are themselves part of Islamic history, even when they interpret the same early events differently.

Source-sensitive points
uncertain
Modern reference works commonly place ʿAli’s birth around 600 CE, but the precise year is not securely established. A later and especially prominent tradition states that he was born inside the Kaʿba; the fame and religious significance of this account are clear, while its exact early documentary basis is not equivalent to the evidence for the approximate date and his Meccan Hashimite origins.
Sources: [1] Reference biography
reported
ʿAli is consistently placed among the earliest converts to Islam. Claims that he was “the first male,” “the first youth,” or simply “the first” depend on how sources classify Khadija, Abu Bakr, Zayd ibn Haritha and ʿAli by age, sex and social category. The underlying early conversion is much less controversial than attempts to produce one universal numerical ranking.
Sources: [1] Reference biography, [2] Early sira chronology
reported
The story that ʿAli slept in the Prophet Muhammad ﷺ’s bed on the night of the Hijra and remained in Mecca to return entrusted property is prominent in early sira and later biography. The narrative is historically important within Muslim memory, but its detailed form is transmitted primarily through biographical reports rather than the strongest canonical hadith collections; individual details therefore carry a different evidentiary profile from the broad fact of ʿAli’s migration and proximity to the Prophet ﷺ.

disputed
The report “For whomever I am his mawla, ʿAli is his mawla” is transmitted in hadith literature, including Jami at-Tirmidhi 3713, graded sahih in the edition represented here. The principal dispute concerns interpretation rather than the mere existence of a pro-ʿAli declaration: Shi‘i tradition reads mawla and the event of Ghadir Khumm as part of a designation to authoritative succession, while Sunni interpretations generally understand the statement in terms of loyalty, love, support or special standing without making it an appointment to the caliphate. Modern scholarship likewise distinguishes the transmitted wording from later doctrinal conclusions drawn from it.

Abu Bakr’s accession after the Prophet Muhammad ﷺ’s death and ʿAli’s absence from the initial Saqifa meeting belong to the early chronology. The theological and political meaning of those events is deeply disputed. Sunni traditions generally regard Abu Bakr’s caliphate as legitimate and later recognize ʿAli as the fourth caliph; Shi‘i traditions hold that ʿAli possessed a prior divinely grounded claim to leadership. Early reports about kinship, consultation, Ghadir Khumm, delayed allegiance and later reconciliation have consequently been arranged into different historical narratives.

disputed
Sahih al-Bukhari reports Fatima’s dispute with Abu Bakr over Fadak and related property, her death about six months after the Prophet Muhammad ﷺ, and a later reconciliation in which ʿAli publicly pledged to Abu Bakr after having not done so during those months. Sunni and Shi‘i historiographies differ sharply over the legal justice of the Fadak decision, the implications of Fatima’s displeasure and what the delayed pledge reveals about ʿAli’s political position. The Bukhari narrative is important evidence, but it did not end the later dispute over how those events should be interpreted.

The Battle of the Camel in 656 involved ʿAli on one side and a coalition associated with Aisha, Talha and al-Zubayr on the other, in the aftermath of ʿUthman’s murder. Sources agree on the broad participants and outcome but differ substantially over the intentions of the leaders, the success of pre-battle negotiations, who initiated fighting and the role of men implicated in ʿUthman’s death. Later Sunni and Shi‘i narratives often moralize the conflict in different directions, so precise assignment of responsibility requires caution.

disputed
The confrontation at Siffin in 657 and the subsequent move to arbitration are basic elements of the chronology of the first civil war. The later literature, however, preserves several competing versions of the arbitration itself. Particularly dramatic stories in which Abu Musa publicly deposes both rivals before ʿAmr ibn al-ʿAs deceives him and confirms Muʿawiya are not transmitted uniformly and are treated differently by modern historians. The political weakening of ʿAli’s coalition and the emergence of Kharijite opposition are more secure than every detail of the famous staged-arbitration story.

ʿAli’s killing in 661 by ʿAbd al-Rahman ibn Muljam is part of the stable historical account, and Ibn Muljam is widely associated with the Kharijite milieu. Details concerning conspiratorial coordination, the exact sequence surrounding the attack and especially the location of ʿAli’s burial are transmitted in varying forms. Najaf became the dominant identification of his tomb in Shi‘i tradition, while early reports also reflect deliberate concealment of the burial place during a period of political danger.
