Musnad Ahmad 30:2709

Hajjaj narrated to us, and Yazid narrated to us, he said: Ibn Abi Dhi'b informed us, from Sa'id al-Maqburi, from Abu Hurayrah, who said: "I am the most similar of you in prayer to the Messenger of Allah, peace and blessings of Allah be upon him." When the Messenger of Allah, peace and blessings of Allah be upon him, said: "Allah hears those who praise Him," he would say: "O Allah, our Lord, and to You is the praise." They both said: And he would say the takbir when he bowed, and when he rose from prostration, and when he raised his head from the two prostrations.
