Saqifah Bani Sa'idah (Arabic: سَقِيفَة بَنِي سَاعِدَة‎, Saqīfah Banī Sāʿdah), commonly known as simply Saqifah, (Arabic: ٱلسَّقِيفَة‎ as-Saqīfah), was a roofed building in Medina used by the Banu Sa'idah clan of the Banu Khazraj tribe. Saqifah is significant as the site where, after Muhammad's death, some of his companions gathered and pledged allegiance to Abu Bakr, electing him as the first Caliph.
