Takbir (Allahu Akbar) in the prayer

 274. Abu Hurairah narrated: Whenever the Messenger of Allah salla alayhi wa sallam stood for the prayer, he said Takbir on starting the prayer and on bowing. After rising from the bowing, he said: ´Sami´ Allahuliman hamida´, and then while standing stright, he used to say: ´Rabbana wa lakal-hamd´. He used to say Takbir on prostrating and on raising his head from prostration. Again, he would say Takbir on prostrating and raising his head. He would do the same in the whole of the prayer until it was completed. And on rising from the second Rak´ah after sitting (for At-Tahiyyat), he used to say Takbir.

Abu Hurairah then said: My prayer resembles that of the Messenger of Allah salla alayhi wa sallam more than anyone of you.
