It is narrated from Hazrat Aisha (may Allah be pleased with her) that sometimes a vessel would be presented to the Prophet (peace and blessings be upon him) while I was in my menstrual period, and I would drink from its water. Then the Prophet (peace and blessings be upon him) would take it and place his mouth at the same spot where I had placed my mouth and drunk from. Similarly, I would take a bone and eat its meat, and the Prophet (peace and blessings be upon him) would take it and place his mouth at the same spot where I had placed my mouth and eaten from.
