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 صلی اللہ علیہ وآلہ وسلم 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.” (Sahih)
