Sunan Abi Dawud Book 2, Hadith 392
The Prophet(peace be upon hm), Abu Bakr, ‘Umar and ‘Uthman used to begin the recitation with “Praise be to Allah, the Lord of the Universe.”
The Messenger of Allah (ﷺ) kept silence between the takbir and the recitation of Qur’an. So I asked him, for whom I would give my father and mother as ransom: What do you say during you period of silence between the takbir and the recitation? He replied (that he said): O Allah, purify me from sins as a white garment is purified from filth. O Allah, wash away my sings with snow, water and hail.
The Messenger of Allah(ﷺ) began prayer with the takbir (Allah is most great) and with reciting “Praise be to Allah, the Lord of the Universe”. And when he bowed, he neither raised up nor lowered down his head, but kept it between the two (conditions). And when he raised his head after bowing, he did not prostrate himself until he stood up straight; and when he raised his head after prostration, he did not prostrate (the second time) until he sat down properly; and he recited al-tahiyyat after every pair of rak’ahs; and when he sat, he spread out his left foot and raised his right. He forbade to sit like the sitting of the devil, and to spread out to hands (on the ground in prostration) like animals. He used to finish prayer with uttering the salutation.
