I prayed behind a Sheikh at Mecca and he said twenty two Takbirs (during the prayer). I told Ibn `Abbas that he (i.e. that Sheikh) was foolish. Ibn `Abbas admonished me and said, "This is the tradition of Abul-Qasim."
Sahih al-Bukhari Book 10, Hadith 183
← Previous Hadith I saw a person praying at Muqam-Ibrahim (the place of Abraham by the Ka`ba) and he was saying Takbir on every bowing, rising, standing and sitting. I asked Ibn `Abbas (about this prayer). He admonished me saying: "Isn't that the prayer of the Prophet?"

Sahih al-Bukhari Book 10, Hadith 182 Next Hadith → Whenever Allah's Messenger (ﷺ) stood for the prayer, he said Takbir on starting the prayer and then on bowing. On rising from bowing he said, "Sami`a llahu liman hamidah," and then while standing straight he used to say, "Rabbana laka-l hamd" (Al- Laith said, "(The Prophet (ﷺ) said), 'Wa laka l-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 then do the same in the whole of the prayer till it was completed. On rising from the second rak`a (after sitting for at-Tahiyyat), he used to say Takbir.
