'A'isha reported:
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ ، وَزُهَيْرُ بْنُ حَرْبٍ ، قَالاَ حَدَّثَنَا وَكِيعٌ ، عَنْ مِسْعَرٍ ، وَسُفْيَانَ ، عَنِ الْمِقْدَامِ بْنِ شُرَيْحٍ ، عَنْ أَبِيهِ ، عَنْ عَائِشَةَ ، قَالَتْ كُنْتُ أَشْرَبُ وَأَنَا حَائِضٌ، ثُمَّ أُنَاوِلُهُ النَّبِيَّ صلى الله عليه وسلم فَيَضَعُ فَاهُ عَلَى مَوْضِعِ فِيَّ فَيَشْرَبُ وَأَتَعَرَّقُ الْعَرْقَ وَأَنَا حَائِضٌ ثُمَّ أُنَاوِلُهُ النَّبِيَّ صلى الله عليه وسلم فَيَضَعُ فَاهُ عَلَى مَوْضِعِ فِيَّ . وَلَمْ يَذْكُرْ زُهَيْرٌ فَيَشْرَبُ .
I would drink when I was menstruating, then I would hand it (the vessel) to the Apostle (ﷺ) and he would put his mouth where mine had been, and drink, and I would eat flesh from a bone when I was menstruating, then hand it over to the Apostle (ﷺ) and he would put his mouth where mine had been. Zuhair made no mention of (the Holy Prophet's) drinking.
