It was narrated that 'Aishah said:
"I would drink while I was menstruating, then I would hand it to the Prophet (ﷺ), and he would put his mouth where mine had been and drink. And I would nibble at the bone on which some bits of meat were left while I was menstruating, then I would give it to the Prophet (ﷺ) and he would put his mouth where my mouth had been." (DE)
