Narrated Abu Huraira: When the Prophet said, Sami`a l-lahu liman hamidah, (Allah heard those who sent praises to Him), he would say, Rabbana wa laka l-hamd. On bowing and raising his head from it the Prophet used to say Takbir. He also used to say Takbir on rising after the two prostrations. (See Hadith No. 656).
