Concerning the urine of an infant boy who is not yet eating solid food
حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ، حَدَّثَنَا أَبُو بَكْرٍ الْحَنَفِيُّ، حَدَّثَنَا أُسَامَةُ بْنُ زَيْدٍ، عَنْ عَمْرِو بْنِ شُعَيْبٍ، عَنْ أُمِّ كُرْزٍ، أَنَّ رَسُولَ اللَّهِ ـ صلى الله عليه وسلم ـ قَالَ بَوْلُ الْغُلاَمِ يُنْضَحُ وَبَوْلُ الْجَارِيَةِ يُغْسَلُ .
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."
