It was narrated that Jami' bin Shaddad said:
"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.'"
