Abu al-Tahir narrated to me, Ibn Wahb narrated to us, from Haywah, that Abu Yunus, the freed slave of Abu Hurayrah, narrated to him, saying: I heard Abu Hurayrah say, from the Messenger of Allah, peace and blessings be upon him, that he said: "The imam is appointed only to be followed. So when he says the takbir, say the takbir; when he bows, bow; when he says, 'Allah hears those who praise Him,' say, 'O Allah, our Lord, to You be praise.' And when he prays standing, pray standing; and when he prays sitting, pray sitting, all of you."
