Sunan Abu Dawood, Chapter: Purification (Kitab Al-Taharah)

AbdurRahman ibn Hasanah reported: I and Amr ibn al-'As went to the Prophet (peace_be_upon_him). He came out with a leather shield (in his hand). He covered himself with it and urinated. Then we said: Look at him. He is urinating as a woman does. The Prophet (peace_be_upon_him), heard this and said: Do you not know what befell a person from amongst Banu Isra'il (the children of Israel)? When urine fell on them, they would cut off the place where the urine fell; but he (that person) forbade them (to do so), and was punished in his grave.
