وَحَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ أَبِي النَّضْرِ، أَنَّ أَبَا مُرَّةَ، مَوْلَى أُمِّ هَانِئٍ بِنْتِ أَبِي طَالِبٍ أَخْبَرَهُ أَنَّهُ، سَمِعَ أُمَّ هَانِئٍ بِنْتَ أَبِي طَالِبٍ، تَقُولُ ذَهَبْتُ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم عَامَ الْفَتْحِ فَوَجَدْتُهُ يَغْتَسِلُ . وَفَاطِمَةُ ابْنَتُهُ تَسْتُرُهُ بِثَوْبٍ .
