The Messenger of Allah ﷺ used to lie down with me while I was menstruating, with a garment between us.
كان رسول الله ﷺ يضطجع معي وأنا حائض، وبيني وبينه ثوب.
Muslim narrated it in the Book of Menstruation (295) through Ibn Wahb, who said, Makhrama informed me, from his father, from Kurayb, the freed slave of Ibn Abbas, who said, "I heard Maymuna." Then he related the hadith.
