"I came to the Messenger of Allah with a son of mine who was not yet eating solid food, and he (the baby) urinated on him. He called for water and sprinkled it over (the urine)."
Sunan Ibn Majah Book 1, Hadith 258
← Previous Hadith "A baby boy was brought to the Prophet who then urinated on him. He sprinkled over it with water and did not wash it."

Sunan Ibn Majah Book 1, Hadith 257 Next Hadith → 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."
