[Machine] "I was a servant of the Prophet ﷺ, and I brought Hassan or Hussein, and the Prophet put him on his chest. They wanted to wash him, so he said, 'Sprinkle him with water, as he is washed with the urine of a little girl and sprinkled with the urine of a boy.' The two sheikhs have mentioned the urination of the baby, a narration from Aisha and Umm Qais bint Muhsin, that the Prophet ﷺ ordered water to be poured on the urine of the baby. As for the mention of the urine of the baby girl, they did not mention it."

كُنْتُ خَادِمَ النَّبِيِّ ﷺ فَجِيءَ بِالْحَسَنِ أَوِ الْحُسَيْنِ فَبَالَ عَلَى صَدْرِهِ فَأَرَادُوا أَنْ يَغْسِلُوهُ فَقَالَ «رُشُّوهُ رَشًّا فَإِنَّهُ يُغْسَلُ بَوْلُ الْجَارِيَةِ وَيُرَشُّ بَوْلُ الْغُلَامِ» «قَدْ خَرَّجَ الشَّيْخَانِ فِي بَوْلِ الصَّبِيِّ حَدِيثَ عَائِشَةَ وَأُمِّ قَيْسٍ بِنْتِ مِحْصَنٍ أَنَّ النَّبِيَّ ﷺ» أَمَرَ بِمَاءٍ فَصُبَّ عَلَى بَوْلِ الصَّبِيِّ « فَأَمَّا ذِكْرُ بَوْلِ الصَّبِيَّةِ فَإِنَّهُمَا لَمْ يُخَرِّجَاهُ» صحيح

"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.'"
