(138) باب بَوْلِ الصَّبِيِّ يُصِيبُ الثَّوْبَ
Narrated Lubabah daughter of al-Harith:
Al-Husayn ibn Ali was (sitting) in the lap of the Messenger of Allah (ﷺ). He passed water on him. I said: Put on (another) clothe, and give me your wrapper to wash. He said: The urine of a female child should be washed (thoroughly) and the urine of a male child should be sprinkled over.
