I heard Humran b. Aban narrate to Abu Burda in this very mosque during the governorship of Bishr that 'Uthman b. Alfan said: The Messenger of Allah ﷺ observed: He who completed ablution as Allah, the Exalted, enjoined upon him, his obligatory prayers would be expiations ˹for his minor sins that he would commit˺ between them.
سَمِعْتُ حُمْرَانَ بْنَ أَبَانَ يُحَدِّثُ أَبَا بُرْدَةَ فِي هَذَا الْمَسْجِدِ فِي إِمَارَةِ بِشْرٍ أَنَّ عُثْمَانَ بْنَ عَفَّانَ قَالَ قَالَ رَسُولُ اللَّهِ ﷺ مَنْ أَتَمَّ الْوُضُوءَ كَمَا أَمَرَهُ اللَّهُ تَعَالَى فَالصَّلوَاتُ الْمَكْتُوبَاتُ كَفَّارَاتٌ لِمَا بَيْنَهُنَّ
