Sunan Ibn Majah 346

It was narrated that `Abdur-Rahman bin Hasanah said:"The Messenger of Allah came out to us holding a small shield in his hand. He put it down, then he sat down and urinated towards it. Some of the people said: 'Look at him, he urinates like a woman!' The Prophet heard that and said: 'Woe to you! Do you not know what happened to one of the children of Israel? If any urine touched any part of their clothes, they would cut that out with scissors. He told them not to do that, so he was tormented in his grave.'" (Da'if) Another chain with similar wording
