باب سُؤْرِ الْحَائِضِ ‏‏
Sunan an-Nasa'i 70
It was narrated that 'Aishah, may Allah be pleased with her, said:
"While I was menstruating, I would nibble meat from a bone, and the Messenger of Allah (ﷺ) would put his mouth where mine had been. And while I was menstruating, I would drink from a vessel and he would put his mouth where mine had been."
أَخْبَرَنَا عَمْرُو بْنُ عَلِيٍّ، قَالَ حَدَّثَنَا عَبْدُ الرَّحْمَنِ، عَنْ سُفْيَانَ، عَنِ الْمِقْدَامِ بْنِ شُرَيْحٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، - رضى الله عنها - قَالَتْ كُنْتُ أَتَعَرَّقُ الْعَرْقَ فَيَضَعُ رَسُولُ اللَّهِ صلى الله عليه وسلم فَاهُ حَيْثُ وَضَعْتُ وَأَنَا حَائِضٌ وَكُنْتُ أَشْرَبُ مِنَ الإِنَاءِ فَيَضَعُ فَاهُ حَيْثُ وَضَعْتُ وَأَنَا حَائِضٌ ‏.‏
