مَنْ يُكَنَّى أَبَا السَّمْحِ أَبُو السَّمْحِ خَادِمُ النَّبِيِّ ﷺ
[Machine] I used to serve the Prophet ﷺ , so whenever he wanted to perform ablution he would say, "Bring me water." I would bring him water in a container and he would call for either Hasan or Husayn, and they would urinate on his chest. Then I would wash him and he would say, "The urine of a girl is to be washed, while the urine of a boy is to be sprinkled."
كُنْتُ أَخْدُمُ النَّبِيَّ ﷺ فَكَانَ إِذَا أَرَادَ أَنْ يَغْتَسِلَ قَالَ «وَلِّنِي» فَأُوَلِّيهِ قَفَاي فَأُتِيَ بِحَسَنٍ أَوْ حُسَيْنٍ فَبَالَ عَلَى صَدْرِهِ فَجِئْتُ أَغْسِلُهُ فَقَالَ «يُغْسَلُ بَوْلُ الْجَارِيَةِ وَيُرَشُّ بَوْلُ الْغُلَامِ»
