It was narrated that Jami' bin Shaddad - AbuSakhrah - said:
"I heard Humran telling Abu Burdah in the mosque that he had heard 'Uthman bin 'Affan narrating that the Prophet had said" 'Whoever performs ablution perfectly as Allah has enjoined, then his prescribed prayer will serve as expiation for what is between them."

حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ جَامِعِ بْنِ شَدَّادٍ أَبِي صَخْرَةَ، قَالَ سَمِعْتُ حُمْرَانَ، يُحَدِّثُ أَبَا بُرْدَةَ فِي الْمَسْجِدِ أَنَّهُ سَمِعَ عُثْمَانَ بْنَ عَفَّانَ، يُحَدِّثُ عَنِ النَّبِيِّ ﷺ قَالَ " مَنْ أَتَمَّ الْوُضُوءَ كَمَا أَمَرَهُ اللَّهُ فَالصَّلَوَاتُ الْمَكْتُوبَاتُ كَفَّارَاتٌ لِمَا بَيْنَهُنَّ " .
