‘Uthman said: I heard the Messenger of Allah (ﷺ) say: “Do you think if there was a river in the courtyard of one of you and he washed himself in it five times each day, would any dirt remain on him? They said: Nothing [would remain on him). He said: `The (five daily) prayers take away sins as water takes away dirt.`
Narrated It was narrated that Abu Hurairah (رضي الله عنه) said:
`Uthman (رضي الله عنه) went to Makkah for Hajj. The wife of Muhammad bin Ja`far bin Abi Talib entered upon him (i.e., her husband) and he spent the night with her. Then the next morning, he (i.e., Muhammad bin Ja`far) came out smelling of perfume and wearing a wrapper saturated with safflower dye. He caught up with the people in weariness before they set out. When `Uthman saw him, he rebuked him and expressed disapproval, saying: Are you wearing something dyed with safflower when the Messenger of Allah (ﷺ) forbade that? `Ali bin Abi Talib (رضي الله عنه) said to him: The Messenger of Allah (ﷺ) did not forbid it to him or you; he only forbade it to me.
Narrated It was narrated from Humran, the freed slave of ‘Uthman, that `Uthman bin `Affan said:
I heard the Messenger of Allah (ﷺ) say: `Whoever does wudoo’ and does it properly, then goes to offer an obligatory prayer and offers it, his sins will be forgiven.”
