"I heard Humran bin Aban tell Abu Burdah in the Masjid that he heard 'Uthman narrating that the Messenger of Allah (ﷺ) said: 'Whoever performs Wudu' completely as commanded by Allah, the five daily prayers will be an expiation for whatever comes in between them.'"
Sunan an-Nasa'i Book 1, Hadith 146
← Previous Hadith "O Abu Ayyub, we missed the general mobilization, but we have been told that whoever prays in the four Masjids will be forgiven his sins." He said: "O son of my brother! I will tell you of something easier than that. I heard the Messenger of Allah (ﷺ) says: 'Whoever performs Wudu' as commanded and prays as commanded, will be forgiven for his previous actions.' Is it not so, O 'Uqbah?" He said: "Yes."

Sunan an-Nasa'i Book 1, Hadith 145 Next Hadith → "I heard the Messenger of Allah (ﷺ) say: 'There is no man who performs Wudu' and does it well, then prays, but when he prays it, he will be forgiven whatever (sins he commits) between that and the next prayer."
