Arabic hadith text
حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، حَدَّثَنَا أَبُو الأَحْوَصِ، عَنْ سِمَاكِ بْنِ حَرْبٍ، عَنْ قَابُوسَ بْنِ أَبِي الْمُخَارِقِ، عَنْ لُبَابَةَ بِنْتِ الْحَارِثِ، قَالَتْ بَالَ الْحُسَيْنُ بْنُ عَلِيٍّ فِي حِجْرِ النَّبِيِّ ـ صلى الله عليه وسلم ـ فَقُلْتُ يَا رَسُولَ اللَّهِ أَعْطِنِي ثَوْبَكَ وَالْبَسْ ثَوْبًا غَيْرَهُ فَقَالَ " إِنَّمَا يُنْضَحُ مِنْ بَوْلِ الذَّكَرِ وَيُغْسَلُ مِنْ بَوْلِ الأُنْثَى "
Translation
It was narrated that Lubabah bint Harith said
"Husain bin 'Ali urinated in the lap of the Prophet and I said: 'O Messenger of Allah, give me your garment and put on another garment.' He said: 'Water should be sprinkled on the urine of a baby boy, and the urine of a baby girl should be washed away.'"
