سنن أبي داود

Umm Qais daughter of Mihsan reported that she came to the Messenger of Allah (ﷺ) with her little son who had not attained the age of eating food. The Messenger of Allah (ﷺ) seated him in his lap, and he urinated on his clothe. He sent for water and sprayed it (over his clothe) and did not wash it.
