Sunan an-Nasa'i, Book 3, Hadith 29 (In-Book) ⓘ

It was narrated from Shuraih that he asked 'Aishah: "Can a woman eat with her husband while she is menstruating?' She said: 'Yes. The Messenger of Allah would call me to eat with him while I was menstruating. He would take a piece of bone on which some bits of meat were left and insist that I take it first, so I would nibble a little from it, then put it down. Then he would take it and nibble from it, and he would put his mouth where mine had been on the bone. Then he would call for a drink and insist that I take it first before he drank from it. So I would take it and drink from it, then put it down, then he would take it and drink from it, putting his mouth where mine had been on the cup.'"

أَخْبَرَنَا قُتَيْبَةُ بْنُ سَعِيدِ بْنِ جَمِيلِ بْنِ طَرِيفٍ، قَالَ أَنْبَأَنَا يَزِيدُ بْنُ الْمِقْدَامِ بْنِ شُرَيْحِ بْنِ هَانِئٍ، عَنْ أَبِيهِ، عَنْ شُرَيْحٍ، أَنَّهُ سَأَلَ عَائِشَةَ هَلْ تَأْكُلُ الْمَرْأَةُ مَعَ زَوْجِهَا وَهِيَ طَامِثٌ قَالَتْ نَعَمْ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَدْعُونِي فَآكُلُ مَعَهُ وَأَنَا عَارِكٌ كَانَ يَأْخُذُ الْعَرْقَ فَيُقْسِمُ عَلَىَّ فِيهِ فَأَعْتَرِقُ مِنْهُ ثُمَّ أَضَعُهُ فَيَأْخُذُهُ فَيَعْتَرِقُ مِنْهُ وَيَضَعُ فَمَهُ حَيْثُ وَضَعْتُ فَمِي مِنَ الْعَرْقِ وَيَدْعُو بِالشَّرَابِ فَيُقْسِمُ عَلَىَّ فِيهِ مِنْ قَبْلِ أَنْ يَشْرَبَ مِنْهُ فَآخُذُهُ فَأَشْرَبُ مِنْهُ ثُمَّ أَضَعُهُ فَيَأْخُذُهُ فَيَشْرَبُ مِنْهُ وَيَضَعُ فَمَهُ حَيْثُ وَضَعْتُ فَمِي مِنَ الْقَدَحِ ‏.‏
