وَحَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ ، وَأَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ جَمِيعًا عَنِ ابْنِ عُيَيْنَةَ ، قَالَ قُتَيْبَةُ حَدَّثَنَا سُفْيَانُ، عَنْ عَمْرٍو ، عَنْ أَبِي الشَّعْثَاءِ ، عَنِ ابْنِ عَبَّاسٍ ، قَالَ أَخْبَرَتْنِي مَيْمُونَةُ ، أَنَّهَا كَانَتْ تَغْتَسِلُ هِيَ وَالنَّبِيُّ صلى الله عليه وسلم فِي إِنَاءٍ وَاحِدٍ .
