Abu Samh said: "I was a servant of the Prophet, and Hasan and Husain was brought to him and (the infant) urinated on his chest. They wanted to wash it, but the Messenger of Allah said: 'Sprinkle water on it, for the urine of a girl should be washed, but the urine of a boy should be sprinkled over with water.'"

It was narrated that Lubabah bint Harith said: "Husain bin 'Ali urinated in the lap of the Prophet and I said: 'O Messenger of Allah, give me your garment and put on another garment.' He said: 'Water should be sprinkled on the urine of a baby boy, and the urine of a baby girl should be washed away.'"

It was narrated from 'Ali that : The Prophet said concerning the urine of a nursing infant: "Water should be sprinkled over the urine of a boy, and the urine of a girl should be washed." Abul-Hasan bin Salamah said: "Ahmad bin Musa bin Ma'qil narrated to us that Abul-Yaman Al-Misri said: 'I asked Shafi'i about the Hadith of the Prophet, "Water should be sprinkled over the urine of a baby boy, and the urine of a baby girl should be washed," when the two types of water (urine) are the same. He said, "This is because the urine of the boy is of water and clay, but the urine of the girl is of flesh and blood." Then he said to me: "Did you understand?" I said: "No." He said: "When Allah the Most High created Adam, He created Eve (Hawwa') from his short rib, so the boy's urine is from water and clay, and the girl's urine is from flesh and blood." Then he said to me: "Did you understand?" I said: "Yes." He said: "May Allah cause you benefit from this."

It was narrated from Umm Kurz that: The Messenger of Allah said: "The urine of a boy should be sprinkled over and the urine of a girl should be washed."
