Umm Salamah narrated: "While I was lying down with the Messenger of Allah (ﷺ) under a blanket, my period came, so I slipped away and put on the clothes I used to wear when I was menstruating. The Messenger of Allah (ﷺ) said: 'Are you menstruating?' I said: 'Yes.' Then he called me and I lied down with him under the blanket."
