سنن النسائي

It was narrated from Abu Salamah bin Abdur-Rahman that: Marwan appointed Abu Hurairah as governor of Al-Madinah. When he stood to offer an obligatory prayer, he would say the takbir, then he said the takbir when he bowed, and when he raised his head from bowing he said: "Sami' Allahu liman hamidah, Rabbana wa lakal-hamd (Allah hears those who praise Him; our Lord, and to You be the praise)." Then he would say the takbir when he went down in prostration, then he said the takbir when he stood up after two rak'ahs, after saying the Tashahhud, and he did that until he had finished the prayer. When he had finished his prayer and said the Salam, he turned to the people in the masjid and said: "By the One in Whose Hand is my soul, I am the one among you whose prayer most closely resembles that of the Messenger of Allah (ﷺ)."
