“The Messenger of Allah ﷺ was praying when he felt the cold, so he said, ‘O Aisha, drape your mirṭ (cloak) over me.’ She answered, ‘I am menstruating.’ He replied, ‘Your menstruation is not in your hand.’ Al-Haythami comments, ‘Its chain is fair.’
A corroborating report comes from Maymunah: the Prophet ﷺ prayed while wearing a mirṭ, part of which covered one of his wives who was menstruating, and he continued the prayer with it upon him. It was recorded by Abu Dawud and Abu ʿAwanah—and by al-Bayhaqi through Abu ʿAwanah—as well as by Ibn Majah and Ahmad, through Sufyan ibn ʿUyaynah › al-Shaybani › ʿAbd Allah ibn Shaddad › her. The wording belongs to Abu Dawud, and Ahmad transmits something similar. Ibn Majah phrases it, “Part of it was on him and part of it on her.” Al-Bayhaqi, reporting from al-Shafiʿi through Sufyan, has: “Some of it was on me and some of it on him.” Its chain is authentic according to the criteria of the two Shaykhs.
Al-Bukhari, Muslim, and Ahmad also report it through other lines from al-Shaybani with the wording: “He would pray while I was lying opposite him, menstruating, and his garment might touch me when he prostrated.”
Another supporting narration comes from Hudhayfah ibn al-Yaman, who said: “I spent a night with the family of the Messenger of Allah ﷺ. The Messenger of Allah ﷺ rose to pray while one end of the quilt was over him and the other end over Aisha, who was menstruating and not praying.”
