Maimunah reported: The Prophet (ﷺ) prayed on a sheet of cloth put on by one of his wives who was menstruating. He was praying while (a part of) it was upon him.
'Aishah said: The Messenger of Allah (ﷺ) would pray at night while I lay by his side during my menstrual period. A sheet of cloth would be partly on me and partly on him.
