It is narrated from Hazrat Aisha (may Allah be pleased with her) that once, during the night, her menstruation began. The Prophet (peace and blessings be upon him) was performing prayer at that time. She showed the Prophet (peace and blessings be upon him) by gesture a cloth on which there was blood. The Prophet (peace and blessings be upon him), while still in prayer, gestured to her to wash that cloth. She washed the blood from the spot, and the Prophet (peace and blessings be upon him) took it and prayed in it.
