(104) باب فِي مُؤَاكَلَةِ الْحَائِضِ وَمُجَامَعَتِهَا
'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.
