Bulugh al-Maram #315

Narrated Abu Hurairah (RA): The Prophet (ﷺ) said: "When you get up to pray, perform ablution perfectly, then face the Qiblah and say: 'Allahu Akbar' (Allah is the Most Great). Then recite a convenient portion of the Qur'an; then bow and remain calmly in that position for a moment, then rise up and stand erect; then prostrate and remain calmly in that position for a moment, then rise up and sit calmly, then prostrate and remain calmly in that position for a moment; then do that throughout your prayer." .
