It is narrated from Sayyida Umm Salama (may Allah be pleased with her) that she said: I became menstruating at a time when I and the Messenger of Allah (peace and blessings be upon him) were under one cloth. So I slipped away, and he (peace and blessings be upon him) said: "Have you become menstruating?" I said: "Yes, O Messenger of Allah! I have been afflicted with that which women are afflicted with." He (peace and blessings be upon him) said: "This is something that has been written upon the daughters of Adam." In any case, I went away, arranged myself, tied a cloth around myself, and then came and lay down with the Messenger of Allah (peace and blessings be upon him) under the blanket.
