Imam Bukhari narrates: Musaddad narrated to us, from Khalid, he said: Sulaiman bin Shaibani narrated to us, from Abdullah bin Shaddad, from Hazrat Maimunah (may Allah be pleased with her), she narrates that
the Messenger of Allah ﷺ was praying and I was in front of him, at that time I was menstruating, sometimes when he made Sajdah, his garment would fall upon me, and he was praying upon a prayer-mat (Musalla).
