Sahih Muslim Book - 3, Hadith - 692

حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ وَزُهَيْرُ بْنُ حَرْبٍ قَالَا حَدَّثَنَا وَكِيعٌ عَنْ مِسْعَرٍ وَسُفْيَانَ عَنْ الْمِقْدَامِ بْنِ شُرَيْحٍ عَنْ أَبِيهِ عَنْ عَائِشَةَ قَالَتْ كُنْتُ أَشْرَبُ وَأَنَا حَائِضٌ ثُمَّ أُنَاوِلُهُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَيَضَعُ فَاهُ عَلَى مَوْضِعِ فِيَّ فَيَشْرَبُ وَأَتَعَرَّقُ الْعَرْقَ وَأَنَا حَائِضٌ ثُمَّ أُنَاوِلُهُ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ فَيَضَعُ فَاهُ عَلَى مَوْضِعِ فِيَّ. وَلَمْ يَذْكُرْ زُهَيْرٌ فَيَشْرَبُ.

It was narrated that 'Aishah said: "I would drink while I was menstruating, then I would pass it to the Prophet (s.a.w) and he would put his mouth at the place where my mouth had been and drink. And I would nibble meat from the bone while I was menstruating, then I would pass it to the Prophet (s.a.w) and he would put his mouth where my mouth had been." Zuhair (one of the narrators) did not mention "and drink."
