Abu Huraira told how on an occasion when God’s Messenger led them in the noon prayer, there was a man at the back of the rows who performed the prayer badly. When he had said the taslim God’s Messenger called out to him, “So and so, do you not fear God? Do you not see how you should pray? You people think that part of what you are doing is hidden from me, but I swear by God that I see behind me just as I see in front of me."
Abu Huraira said that God’s Messenger used to observe a period of silence between the takbir and the recitation of the Qur an, so he addressed him thus, “Messenger of God, for whom I would give my father and mother as ransom, what do you say during your period of silence between the takbir and the recitation?” He replied that he said, “O God, remove my sins far from me as Thou hast removed the East far from the West. O God, purify me from sins as a white garment is purified from filth. O God, wash away my sins with water, snow and hail.”
‘Alqama said that Ibn Mas'ud suggested leading them in prayer in the way God’s Messenger had performed it. He prayed, raising his hands only once, along with the takbir at the beginning.
Tirmidhi, Abu Dawud and Nasa’i transmitted it, and Abu Dawud said it is not sahih put this way.
