Yahya related to me from Malik from Hisham ibn Urwa from his father that A'isha, the wife of the Prophet ﷺ said, "An infant boy was brought to the Messenger of Allah ﷺ and it urinated on him. The Messenger of Allah ﷺ called for some water and rubbed over the urine with it."
عَنْ عَائِشَةَ زَوْجِ النَّبِيِّ ﷺ أَنَّهَا قَالَتْ أُتِيَ رَسُولُ اللَّهِ ﷺ بِصَبِيٍّ فَبَالَ عَلَى ثَوْبِهِ فَدَعَا رَسُولُ اللَّهِ ﷺ بِمَاءٍ فَأَتْبَعَهُ إِيَّاهُ
