Bulugh al-Maram 290 — The Book of Prayer

A'isha Narrated from:

Allah's Messenger (ﷺ) used to begin the Salat (prayer) with Takbir (Allahu Akbar - Allah is the Most Great) and the recitation with Alhamdu lillahi Rabbil' alamin (praise is to Allah, the Rabb of the universe)." And when he bowed down, he neither kept his head up nor bent it down, but kept it between that (two positions).When he raised his head from the bowing position, he did not prostrate till he had stood erect; and when he raised his head after a prostration, he did not prostrate again till he had sat up. And at the end of every two Rak'ah he said the Tahiyyah, and he used to sit on his left foot and position he right one vertically, and he prohibited the devil's way of sitting on the buttocks. He forbade people to spread out their arms like a wild beast. And he used to finish the prayer with the Taslim (i.e. saying As-Salamu 'alaikum).[Reported by Muslim and it has an 'illa (defect)].
