Zaynab bint Abi Salamah (may Allah be pleased with her) reports from her mother, who said: Once I was with the Messenger of Allah (peace and blessings be upon him) under a single sheet when my period began. I slipped away from there and took my menstruation clothes. He (peace and blessings be upon him) said: "What is the matter with you? Has your period begun?" I said: Yes. Then he (peace and blessings be upon him) called me and brought me in with him under the sheet. She said: The Messenger of Allah (peace and blessings be upon him) and I used to perform the ritual bath (ghusl) for janabah from a single vessel, and he (peace and blessings be upon him) used to kiss while fasting.
