Full Sharh — Musnad Ahmad 472
حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنْ جَامِعِ بْنِ شَدَّادٍ، قَالَ سَمِعْتُ حُمْرَانَ بْنَ أَبَانَ، يُحَدِّثُ أَبَا بُرْدَةَ فِي الْمَسْجِدِ أَنَّهُ سَمِعَ عُثْمَانَ بْنَ عَفَّانَ، يُحَدِّثُ عَنْ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَنَّهُ قَالَ مَنْ أَتَمَّ الْوُضُوءَ كَمَا أَمَرَهُ اللَّهُ فَالصَّلَوَاتُ الْمَكْتُوبَاتُ كَفَّارَاتٌ لِمَا بَيْنَهُنَّ.
English Translation
It was narrated that Jami` bin Shaddad said:: I heard Humran bin Aban telling Abu Burdah in the mosque that he heard `Uthman bin `Affan (رضي الله عنه) narrate from the Prophet (ﷺ) that he said: “Whoever does wudoo’ properly as enjoined by Allah, the prescribed prayers will be expiations for whatever comes between them.`
