Mukhtasar Bukhari (Abridged) 222 — Book of Menstruation

Umm al-Mu'mineen Maymunah (may Allah be pleased with her) says that when she was menstruating, she would not pray, and she would lie down right in front of the place where the Messenger of Allah (peace and blessings be upon him) prayed. The Prophet (peace and blessings be upon him) would pray on his sheet, and when he prostrated, some part of his garment would touch me.
