‘Ali related that the Prophet (SAW) said regarding the urine of nursing children: a boy’s urine should get sprinkled, and a girl’s urine should get washed off. Abu Al-Hasan ibn Salama said: Ahmad ibn Musa ibn Ma’qil related to us that Abu Al-Yaman Al-Misri said: I asked Al-Shafi’i about the hadith of the Prophet (SAW) – water should be sprinkled on a boy’s urine, and a girl’s urine should be washed – but both of these urines are the same. He replied: This is because a boy’s urine is from water and clay, while a girl’s urine is from flesh and blood. Then he asked me: Do you understand? (Or maybe he said: Have you grasped it?) I said: No. He said: Indeed Allah Most High, when He created Adam, Eve was created from his short rib, and so a boy’s urine became of water and clay, and a girl’s urine became of flesh and blood. He said to me: Do you understand? I said: Yes. He said to me: May Allah make this of use to you.
