Sunan Ibn Majah, Book 1, Hadith 686 (In-Book) ⓘ

It was narrated that 'Aishah said: "I used to eat the meat from a bone when I was menstruating, then the Messenger of Allah would take it and put his mouth where my mouth had been. And I would drink from a vessel, and the Messenger of Allah would take it and put his mouth where my mouth had been, and I was menstruating."

حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، عَنِ الْمِقْدَامِ بْنِ شُرَيْحِ بْنِ هَانِئٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ كُنْتُ أَتَعَرَّقُ الْعَظْمَ وَأَنَا حَائِضٌ، فَيَأْخُذُهُ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ فَيَضَعُ فَمَهُ حَيْثُ كَانَ فَمِي وَأَشْرَبُ مِنَ الإِنَاءِ فَيَأْخُذُهُ رَسُولُ اللَّهِ ـ صلى الله عليه وسلم ـ فَيَضَعُ فَمَهُ حَيْثُ كَانَ فَمِي وَأَنَا حَائِضٌ ‏.‏
