صحیح مسلم · Hadith 1111

A'isha reported: The Messenger of Allah ( ‌صلی ‌اللہ ‌علیہ ‌وسلم ‌ ) used to begin prayer with takbir (saying Allahu Akbar) and the recitation: Praise be to Allah, the Lord of the Universe. When he bowed he neither kept his head up nor bent it down, but kept it between these extremes; when he raised his head after bowing he did not prostrate himself till he had stood erect; when he raised his head after prostration he did not prostrate himself again till he sat up. At the end of every two rak'ahs he recited the tahiyya; and he used to place his left foot flat (on the ground) and raise up the right; he prohibited the devil's way of sitting on the heels, and he forbade people to spread out their arms like a wild beast. And he used to finish the prayer with the taslim.
