`Uthman sat down one day and we sat down with him. The Mu’adhdhin came to him and `Uthman called for water in a vessel which I thought would contain one mudd. He did wudoo`, then he said: I saw the Messenger of Allah (ﷺ) doing wudoo’ as I have just done it, then he said: `Whoever does wudoo` as I have just done, then gets up and prays Zuhr, will be forgiven for (whatever sins he committed) between it and Fajr; then if he prays `Asr. he will be forgiven so? (whatever sins he committed) between it and Zuhr, then if he prays Maghrib, he will be forgiven for (whatever sins he committed) between it and ‘Asr, then if he prays Isha‘, he will be forgiven for (whatever sins he committed) between it and Maghrib. Then he may spend the night indulging in physical pleasure, then if he gets up and does wudoo’ and prays Fajr, he will be forgiven for (whatever sins he committed) between it and `Isha`. These are the good deeds that remove the evil deeds (cf. 11:114).” They said: These are the good deeds, but what are the good righteous deeds that last (cf. 18:46), O` Uthman? He said: They are (the words)La Ilaha Illallah, wa subhanallah wal-hamdu Lillah wallahu akbar, wa la hawla wa la quwwata illa billah ( There is no god but Allah, praise be to Allah, Allah is most great and there is no power and no strength except with Allah)
