Lady Aisha Siddiqa (may Allah be pleased with her) narrates: Sometimes I would bring a vessel to the service of the Prophet Muhammad (peace be upon him). I would drink from that vessel first, then the Prophet Muhammad (peace be upon him) would take that vessel and place his mouth at the spot where I had placed my mouth. Sometimes I would take a bone with some meat on it and eat from it, then the Prophet Muhammad (peace be upon him) would take that bone and place his mouth at the spot where I had placed my mouth, and he would eat from it, even though I was in a state of menstruation at that time.
