Sunan Abi Dawud 42

سنن أبي داود#42Da'if

Narrated Aisha, Ummul Mu'minin: The Prophet (ﷺ) urinated and Umar was standing behind him with a jug of water. He said: What is this, Umar? He replied: Water for you to perform ablution with. He said: I have not been commanded to perform ablution every time I urinate. If I were to do so, it would become a sunnah
