(9) باب سُؤْرِ الْحَائِضِ
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 has been. And while I was menstruating, I would drink from a vessel and he would put his mouth where mine had been."
