Musannaf Ibn Abi Shaybah 1016 — A woman whose clothes are stained

Adi bin Dinar said: Sayyidah Umm Husayn (may Allah be pleased with her) asked the Messenger of Allah (peace and blessings be upon him): If menstrual blood gets on a garment, what should be done? He said: "Scrape it off with a piece of wood, then wash it with water and lote-tree leaves, then pray in that same garment."
