Narrated Sahl:
When the helmet of the Prophet was smashed on his head and blood covered his face and one of his
front teeth got broken, `Ali brought the water in his shield and Fatima the Prophet's daughter) washed
him. But when she saw that the bleeding increased more by the water, she took a mat, burnt it, and
placed the ashes on the wound of the Prophet and so the blood stopped oozing out.
