It is narrated from Hazrat Umm Salamah (may Allah be pleased with her) that once I was with the Prophet (peace and blessings be upon him) under a blanket when my menstruation started. I began to move away, so the Prophet (peace and blessings be upon him) said, "Has your menstruation started?" I replied, "O Messenger of Allah, I am experiencing the same condition that other women experience." The Prophet (peace and blessings be upon him) said, "This is the thing that has been decreed for all the daughters of Adam (peace be upon him)." Then I left, set myself right, tied a cloth, and then returned and lay under the blanket with the Prophet (peace and blessings be upon him).
