Yahya related to me from Malik from Hisham ibn Urwa from his father that A'isha, the wife of the Prophet, may Allah bless him and grant him peace, said, "An infant boy was brought to the Messenger of Allah, may Allah bless him and grant him peace, and it urinated on him. The Messenger of Allah, may Allah bless him and grant him peace, called for some water and rubbed over the urine with it."
