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), and I would be menstruating and would drink from it, 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. In the same way, 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.
