Sayyiduna Sahl bin Sa'd (may Allah be pleased with him) narrated that when it was the day of the Battle of Uhud and the polytheists had withdrawn from the Messenger of Allah (peace and blessings be upon him) and his Companions, the women went out to help the Messenger of Allah (peace and blessings be upon him) and the Companions, and among them was the daughter of the Messenger of Allah (peace and blessings be upon him), Sayyidah Fatimah (may Allah be pleased with her). When she met the Messenger of Allah (peace and blessings be upon him), she embraced him and began washing his wounds with water, but the blood only increased. When she saw that, she took a piece of a mat and burned it in the fire, then placed it on the wound and pressed it until it stuck to the wound and the blood stopped.
