Concerning the urine of an infant boy who is not yet eating solid food
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَعَلِيُّ بْنُ مُحَمَّدٍ، قَالاَ حَدَّثَنَا وَكِيعٌ، حَدَّثَنَا هِشَامُ بْنُ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ، قَالَتْ أُتِيَ النَّبِيُّ ـ صلى الله عليه وسلم ـ بِصَبِيٍّ فَبَالَ عَلَيْهِ فَأَتْبَعَهُ الْمَاءَ وَلَمْ يَغْسِلْهُ .
It was narrated that 'Aishah said: "A baby boy was brought to the Prophet (ﷺ) who then urinated on him. He sprinkled over it with water and did not wash it."
