It is narrated from Sayyida Aisha (may Allah be pleased with her), she says: A vessel would be brought to the Messenger of Allah (peace and blessings be upon him), I would drink from it first while I was menstruating, then the Prophet (peace and blessings be upon him) would take the vessel and place his mouth where my mouth had been. And I would take a bone with meat on it and eat from it by gnawing the meat off, then the Prophet (peace and blessings be upon him) would take it and place his mouth where my mouth had been.
