(Second chain) Mutarrif says: I was sitting with some Qurayshi individuals when a man came and began to pray, performing bowing and prostration, then prayed again, performing bowing and prostration, and did not sit. I said: By Allah! I think this servant does not even know whether he has prayed an even or odd number of rak‘ahs. The people said: Why don’t you go to him and tell him? So I said: O servant of Allah! I think you do not even know whether you have prayed an even or odd number of rak‘ahs. He said: But Allah Almighty knows; I heard the Messenger of Allah, peace and blessings be upon him, say: Whoever prostrates to Allah Almighty, Allah will write for him a good deed through it, erase a bad deed, and raise him one degree. I said: Who are you? He said: I am Abu Dharr. Hearing this, I returned to my companions and said: May Allah give you a bad reward on behalf of those who sit, you instructed me to teach one of the companions of the Messenger of Allah, peace and blessings be upon him.
