What were the words uttered by the Prophet Muhammad (saw) when he said, "Sami`a l-lahu liman hamidah," and upon bowing and raising his head from it?
 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).
