Yahya ibn Yahya, Qutaybah ibn Sa'id, Abu Bakr ibn Abi Shaybah, 'Amr al-Naqid, Zuhayr ibn Harb, and Abu Kurayb all narrated to us from Sufyan—Abu Bakr said: Sufyan ibn 'Uyaynah narrated to us—from al-Zuhri, who said: I heard Anas ibn Malik say: The Prophet, peace and blessings be upon him, fell from a horse and his right side was injured. We entered upon him to visit him, and the time for prayer came. He led us in prayer while sitting, and we prayed behind him sitting. When he finished the prayer, he said: "The imam is appointed only to be followed. So when he says the takbir, say the takbir; when he prostrates, prostrate; when he raises, raise; and when he says, 'Allah hears those who praise Him,' say, 'Our Lord, to You be praise.' And if he prays sitting, then pray sitting, all of you."
