Sunan an-Nasa'i 282
It was narrated that 'Aishah said:
"I would drink while I was menstruating, then I would hand it to the Prophet (ﷺ), and he would put his mouth where mine had been and drink. And I would nibble at the bone on which some bits of meat were left while I was menstruating, then I would give it to the Prophet (ﷺ) and he would put his mouth where my mouth had been."
أَخْبَرَنَا مَحْمُودُ بْنُ غَيْلاَنَ، قَالَ حَدَّثَنَا وَكِيعٌ، قَالَ حَدَّثَنَا مِسْعَرٌ، وَسُفْيَانُ، عَنِ الْمِقْدَامِ بْنِ شُرَيْحٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، - رضى الله عنها - قَالَتْ كُنْتُ أَشْرَبُ وَأَنَا حَائِضٌ وَأُنَاوِلُهُ النَّبِيَّ صلى الله عليه وسلم فَيَضَعُ فَاهُ عَلَى مَوْضِعِ فِيَّ فَيَشْرَبُ وَأَتَعَرَّقُ الْعَرْقَ وَأَنَا حَائِضٌ وَأُنَاوِلُهُ النَّبِيَّ صلى الله عليه وسلم فَيَضَعُ فَاهُ عَلَى مَوْضِعِ فِيَّ ‏.‏
