حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ حَدَّثَنَا شُعْبَةُ عَنْ جَامِعِ بْنِ شَدَّادٍ قَالَ سَمِعْتُ حُمْرَانَ بْنَ أَبَانَ يُحَدِّثُ عَنْ عُثْمَانَ رَضِيَ اللَّهُ عَنْهُ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَنْ أَتَمَّ الْوُضُوءَ كَمَا أَمَرَهُ اللَّهُ عَزَّ وَجَلَّ فَالصَّلَوَاتُ الْمَكْتُوبَاتُ كَفَّارَاتٌ لِمَا بَيْنَهُنَّ
مسند امام احمد بن حنبل · Hadith 406
It was narrated that 'Uthman (RA) said: The Messenger of Allah (PBUH) said: "Whoever does wudoo' as Allah, may he be glorified and exalted, has commanded him, the prescribed prayers will be an expiation for [whatever sins he commits] between them."
