copy of
Chronology of Ancient Nations, illustrated by Ibn al-Kutbi The historicity of the Ghadir Khumm is rarely disputed within the Muslim community, as its recorded tradition is "among the most extensively acknowledged and substantiated ()" in classical Islamic sources. Nevertheless, several variations exist in the early sources, and there is a significant weight of different accounts. The narrative of the Ghadir Khumm is, for instance, preserved in
Chronology of Ancient Nations by the Sunni polymath
al-Biruni (), which survives in an early fourteenth-century
Ilkhanid copy by Ibn al-Kutbi. The Shia inclination of those responsible for this copy is evident from its illustrations of Ali, including one entitled
The Investiture of Ali at Ghadir Khumm. Accounts of the Ghadir Khumm appear elsewhere in both Sunni and Shia sources, and these accounts have occasionally been used interchangeably without sectarian prejudice. For instance, the Shia scholar
Abdul Hosein Amini () relied on Sunni and Shia sources to list over a hundred companions and eighty-four who had recounted the event, most of whom are now counted among Sunnis. Similar efforts were undertaken by the Shia authors
Hamid H. Musavi () and
Hussein A. Mahfouz (). Other early accounts of the event include those by the Shia-leaning historian
al-Ya'qubi (), and by the Sunni scholars Ibn Hanbal, Ibn Kathir,
Ibn Asakir ()
, al-Tirmidhi (),
al-Nasa'i (),
Ibn Maja (),
Ibn al-Athir (),
Ibn Abd al-Barr (),
Ibn Abd Rabbih (), and
Jahiz (). Some Sunni historians, such as
al-Tabari (),
Ibn Hisham (), and
Ibn Sa'd (), have nonetheless made little or no mention of the Ghadir Khumm, perhaps because the event supports the Shia legitimist claims, or perhaps they wanted to avoid angering their Sunni rulers by supporting the Shia cause. Consequently, Western authors, whose works were based on these authors, also make little reference to the Ghadir Khumm. Even though the Ghadir Khumm is absent from , its author narrates how Muhammad publicly dismissed some complaints about the conduct of Ali in
Yemen in the same "chronological slot" as the Ghadir Khumm. The Islamicist
Maria M. Dakake thus suggests that al-Tabari deliberately replaced the Ghadir Khumm tradition with another one that praised Ali but lacked any spiritual and legitimist implications in favor of Shia. Alternatively, in the ninth-century
Baghdad, some among the Sunni group
Ahl al-Hadith apparently denied the event, which may have prompted al-Tabari to refute their claims in his nonextant book
, or in his unfinished . Similarly, as a senior employee of the Shia
Buyid dynasty, the Shia theologian
Sharif al-Radi () does not mention the Ghadir Khumm in his
, possibly to avoid the ire of the Sunni
Abbasids.
Links to the Qur'an In Shia and some Sunni sources, two verses of the Qur'an are associated with the Ghadir Khumm: verse 5:3, which announces the perfection of Islam, and verse 5:67, which urges Muhammad to fulfill his divine instructions. The latter, sometimes known as the
verse of (, ), has been linked to the Ghadir Khumm by the Sunni exegetes
al-Suyuti () and
al-Razi (), and the Shi'a exegete
al-Qumi (), among others. The verse of warns Muhammad: Revealed before the Ghadir Khumm, according to the Shi'a, this verse spurred Muhammad to deliver his announcement about 'Ali, which he had delayed fearing the reaction of some of his companions. Sunnis offer different views, one of which connects this verse to Muhammad's criticism of
Jews and
Christians. Nevertheless, the verse of is highly likely linked to the events that followed the Farewell Pilgrimage, including the Ghadir Khumm, because chapter (surah|)
five of the Qur'an is often associated with Muhammad's final years in Medina. Verse 5:3 of the Qur'an, also known as the
verse of (, ), is similarly connected to the Ghadir Khumm in some Sunni reports by al-Tabari and the Sunni exegete
al-Baghdadi (), and by the Shia exegete
al-Tusi (), among others. In contrast, most Sunni commentators associate this verse with the Farewell Pilgrimage, and this is also the opinion of al-Ya'qubi. Among various Sunni views, the verse of may refer to the establishment of the rites for Hajj during the Farewell Pilgrimage or the closure of Islamic legislation with the revelation of dietary instructions in the remainder of this verse, although some injunctions about were possibly revealed after this verse. The verse of includes the passage:
Other literary references in a manuscript by the
Ottoman Sufi writer and poet Lami'i, late sixteenth century The Ghadir Khumm has also been preserved in the Arabic literature. The earliest such instance is a disputed poem attributed to
Hassan ibn Thabit (), who accompanied Muhammad during the pilgrimage. For instance, the poem is quoted by the prominent Shia theologian
al-Mufid (). The poem appears also in some other Shia and Sunni sources, according to the Islamicist
Husain M. Jafri (). Included in this poem is the verse, "Stand up, O Ali, for I find only you to be an imam and a guide after I [Muhammad] depart." In regards to its authenticity,
Mohammad A. Amir-Moezzi, another expert, does not find this attribution problematic, while Jafri considers it highly improbable that these events would have passed unrecorded by Ibn Thabit, who was the "official poet-reporter of Muhammad." By contrast, the Islamicists
Josef Horovitz () and
Ignác Goldziher () reject the veracity of this poem. The Shia
al-Kumayt ibn Zayd () is another early poet who composed verses on the same theme.
Historical references On one occasion during his caliphate, Ali is known to have asked Muslims to come forward with their testimonies about the Ghadir Khumm. In doing so, he may have publicly laid claim to a spiritual and political authority greater than others, particularly his predecessors. Muhammad's statement at the Ghadir Khumm, "O God, befriend the friend of Ali and be the enemy of his enemy," was likely the standard formula for pledging allegiance at that time. Indeed, Ali and his son
Hasan both demanded a similar pledge from their supporters during their caliphates. The hadith of the is also cited by
Ammar ibn Yasir, a companion of Muhammad, to support the legitimacy of Ali's caliphate in the account of the Shia historian
Ibn A'tham al-Kufi (ninth century) of the negotiations before the
Battle of Siffin (657). This might be the earliest such reference in historical sources. ==Interpretation==
