Sunan An-Nasai, Chapter: The Book of Purification

"The Messenger of Allah (saw) came out to us with a small leather shield in his hand. He put it down, then he sat behind it and urinated toward it. Some of the people said: 'Look, he is urinating like a woman.' He heard that and said: 'Do you not know what happened to the companion of the Children of Israel? If they got any urine on themselves they would clip that part of their garments off. Their companion told them not to do that and he was punished in his grave.'" (Daif)
