The recitation of whatever is available

 282. Abu Hurairah narrated: The Messenger of Allah salla alayhi wa sallam entered the mosque and a man also entered therein adn performed prayer and then came and greeted the Messenger of Allah salla alayhi wa sallam. The Messenger of Allah salla alayhi wa sallam returned his greeting and said: ´´Go back and pray, for you have not prayed.´´ The man again prayed as he prayed before, and came to the Prophet salla alayhi wa sallam and greeted him. The Messenger of Allah salla alayhi wa sallam said, ´´Wa alaikas-Salam´´ (return the greeting) and said, ´´Go back and pray for you have not prayed.´´ This was repeated three times. Upon this the man said, ´´By Him Who has sent you with truth, I can not do better than this. Teach me.´´ He said: ´´When you get up to pray, say Takbir, and then recite whatever you can conceniently from the Qur´an, then bow down and remain quietly in that posture; then raise yourself and stand stright; then prostrate yourself and remain quietly in that posture, then raise yourself and sit quietly; and do that throughout all your prayers.´´
