Narrator:Abu as-Samh
حَدَّثَنَا مُجَاهِدُ بْنُ مُوسَى، وَعَبَّاسُ بْنُ عَبْدِ الْعَظِيمِ الْعَنْبَرِيُّ، - الْمَعْنَى - قَالاَ حَدَّثَنَا عَبْدُ الرَّحْمَنِ بْنُ مَهْدِيٍّ، حَدَّثَنِي يَحْيَى بْنُ الْوَلِيدِ، حَدَّثَنِي مُحِلُّ بْنُ خَلِيفَةَ، حَدَّثَنِي أَبُو السَّمْحِ، قَالَ كُنْتُ أَخْدُمُ النَّبِيَّ صلى الله عليه وسلم فَكَانَ إِذَا أَرَادَ أَنْ يَغْتَسِلَ قَالَ " وَلِّنِي قَفَاكَ " . فَأُوَلِّيهِ قَفَاىَ فَأَسْتُرُهُ بِهِ فَأُتِيَ بِحَسَنٍ أَوْ حُسَيْنٍ - رضى الله عنهما - فَبَالَ عَلَى صَدْرِهِ فَجِئْتُ أَغْسِلُهُ فَقَالَ "
يُغْسَلُ مِنْ بَوْلِ الْجَارِيَةِ وَيُرَشُّ مِنْ بَوْلِ الْغُلاَمِ "
Abu As-Samh reported: I used to serve the Prophet (may Allah's peace and blessings be upon him) and whenever he wanted to take a bath, he would say: "Turn the other way." So I would turn my back and screen him with it. Al-Hasan or Al-Husayn was brought to him once, and (the infant) urinated on his chest. When I wanted to wash it, the Messenger of Allah (may Allah’s peace and blessings be upon him) said: "The urine of a girl should be washed, but the urine of a boy should be splashed with water."
Reported by Abu Dawud (No. 376) and An-Nasa’i (No. 304).
