The Saqifah of Banu Sa'ida

Muhammad died in Medina in 632 without having named an unambiguous successor, and the community he left behind had no established procedure for choosing one. Word of his death had not even fully settled before a group of the Ansar, the Medinan converts who had sheltered the Muslim community after its emigration from Mecca, gathered at the meeting hall of the Banu Sa'ida clan to discuss choosing a leader from among themselves. Sa'd ibn Ubadah, a senior figure among the Khazraj tribe, put himself forward, arguing the Ansar had earned the right to lead the community they had protected.

Abu Bakr and Umar, both close companions of Muhammad from the Muhajirun who had emigrated with him from Mecca, learned of the gathering and hurried to it rather than let the Ansar settle the question alone. Abu Bakr's argument was blunt: the wider Arab tribes would never accept the rule of anyone outside Muhammad's own tribe, the Quraysh, however deserving the Ansar's claim on grounds of service. Tempers ran high enough that a scuffle broke out around Sa'd ibn Ubadah himself. The turning point came when the Banu Aws, a rival Medinan tribe to the Khazraj, threw their support behind Abu Bakr rather than see a Khazraj leader installed, and Umar's pledge of allegiance to Abu Bakr, followed by others gathering in the hall, settled the question before most of the wider community, including Muhammad's own household, had learned a meeting was taking place at all.

Ali ibn Abi Talib, Muhammad's cousin and son-in-law, was not at the Saqifah. He was occupied, alongside other close relatives, preparing Muhammad's body for burial, and Shia and Sunni sources broadly agree he was not part of the deliberation that chose Abu Bakr. What they do not agree on is what that absence means. Sunni tradition reads the Saqifah as a legitimate, if improvised, act of communal consultation that produced a rightly guided successor; the fact that the wider community, Ali included, eventually pledged allegiance to Abu Bakr closes the question rather than leaving it open.

Shia tradition reads the same absence very differently: as evidence that a decision of this consequence was made without the one man Shia sources hold Muhammad had already designated, at Ghadir Khumm, as his rightful successor. Ali's own pledge of allegiance did not come until roughly six months later, after Fatima's death, and some Shia accounts describe considerable pressure, including a threat against his household, brought to bear on him in the meantime, a specific claim Sunni sources reject in that form even where they acknowledge Ali's delay. The disagreement is not really about what happened in the hall on that single day; it is about what a rightful succession requires, kinship and prior designation against communal consensus, and that argument, opened at the Saqifah, has never fully closed.
