Hadith 1:259
Sahih (Al-Albani)
'Aishah said:
I would eat flesh from a bone when I was menstruating, then hand it over to the Prophet(ﷺ) and he would put his mouth where I had put my mouth: I would drink, then hand it over to him, and he would put his mouth( at the place) where I drank.
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا عَبْدُ اللَّهِ بْنُ دَاوُدَ، عَنْ مِسْعَرٍ، عَنِ الْمِقْدَامِ بْنِ شُرَيْحٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ كُنْتُ أَتَعَرَّقُ الْعَظْمَ وَأَنَا حَائِضٌ، فَأُعْطِيهِ النَّبِيَّ صلى الله عليه وسلم فَيَضَعُ فَمَهُ فِي الْمَوْضِعِ الَّذِي فِيهِ وَضَعْتُهُ وَأَشْرَبُ الشَّرَابَ فَأُنَاوِلُهُ فَيَضَعُ فَمَهُ فِي الْمَوْضِعِ الَّذِي كُنْتُ أَشْرَبُ مِنْهُ
