Sahih Bukhari

Narrated Abu Huraira:When the Prophet (ﷺ) 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 (ﷺ) used to say Takbir. He also used to say Takbir on rising after the two prostrations. (See Hadith No)
