Abu Hurairah said:

When the Messenger of Allahﷺ entered the mosque, a man also entered it and prayed. He then came and saluted the Messenger of Allahﷺ. The Messenger of Allahﷺ returned the salutation and said to him: Go back and pray, for you have not prayed. The man returned and prayed as he prayed before. He then came to prophetﷺ and saluted him. The Messenger of Allahﷺ said to him: “ And upon you be peace. “ Go back and pray, for you have not prayed. He did so three times. Then the man said: By Him who has sent you(as a Prophet) with truth; I cannot do better than this; so teach me. He said: When you get up to pray, utter the takbir(Allah is most great); then recite a convenient portion of the Qur’an; then bow and remain quietly in that position; then sit and remain quietly in that position; then raise yourself and stand erect: then prostrate yourself and remain quietly in that position; then sit and remain quietly in that position; then do that throughout all your prayer.

Abu Dawud said: Al-Qa’nabi reported this tradition from Sa’id b. Abi Sa’Id on the authority of Abu Hurairah. This version has the wording in the last: When you do this, then your prayer is completed. If you omit anything form this, you omit that much from your prayer. This version also has the wording: when you get up for praying, perform the abulation perfectly.
