Sahih Muslim Book - 2, Hadith - 547

حَدَّثَنَا عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ حَدَّثَنَا أَبِي ح و حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى وَابْنُ بَشَّارٍ قَالَا حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ قَالَا جَمِيعًا حَدَّثَنَا شُعْبَةُ عَنْ جَامِعِ بْنِ شَدَّادٍ قَالَ سَمِعْتُ حُمْرَانَ بْنَ أَبَانَ يُحَدِّثُ أَبَا بُرْدَةَ فِي هَذَا الْمَسْجِدِ فِي إِمَارَةِ بِشْرٍ أَنَّ عُثْمَانَ بْنَ عَفَّانَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَنْ أَتَمَّ الْوُضُوءَ كَمَا أَمَرَهُ اللَّهُ تَعَالَى فَالصَّلَوَاتُ الْمَكْتُوبَاتُ كَفَّارَاتٌ لِمَا بَيْنَهُنَّ. هَذَا حَدِيثُ ابْنِ مُعَاذٍ وَلَيْسَ فِي حَدِيثِ غُنْدَرٍ فِي إِمَارَةِ بِشْرٍ وَلَا ذِكْرُ الْمَكْتُوبَاتِ.

It was narrated that Jami' bin Shaddad said: "I heard Humran bin Aban telling Abu Burdah in this Masjid, during the governorship of Bishr, that 'Uthman bin 'Affan said: 'The Messenger of Allah (s.a.w) said: "Whoever performs Wudu' properly as enjoined by Allah the Most High, then the five prescribed prayers will be an expiation for whatever (of sin) comes in between." This is the Hadith of (one of the narrators) Ibn Mu'adh. In the Hadith of Ghundar (one of the narrators) it does not mention the governorship of Bishr or the obligatory prayers.
