ahmad:26877ʿAffān And Bahz > Ḥammād b. Salamah > ʿAṭāʾ al-Khurāsānī > Lubābah Um al-Faḍl > Kānat Turḍiʿ al-Ḥasan or al-Ḥusayn

[Machine] The Messenger of Allah ﷺ came and lay down in a place that had been sprinkled with water. He placed his hand on his stomach, and then his stomach rumbled. I saw urine flowing onto his stomach, so I got close to pour some water on it. The Messenger of Allah ﷺ said, "O Umm al-Fadl, the urine of a boy is simply poured over, while the urine of a girl is washed away." Bahz said: "a wash means washing with water." 'Affan narrated this hadith to us, from Hammad, who narrated it from Humayd. 'Ata' used to narrate it from Abu 'Iyad, from Lubabah.

فَجَاءَ رَسُولُ اللهِ ﷺ فَاضْطَجَعَ فِي مَكَانٍ مَرْشُوشٍ فَوَضَعَهُ عَلَى بَطْنِهِ فَبَالَ عَلَى بَطْنِهِ فَرَأَيْتُ الْبَوْلَ يَسِيلُ عَلَىبَطْنِهِ فَقُمْتُ إِلَى قِرْبَةٍ لِأَصُبَّهَا عَلَيْهِ فَقَالَ رَسُولُ اللهِ ﷺ يَا أُمَّ الْفَضْلِ إِنَّ بَوْلَ الْغُلَامِ يُصَبُّ عَلَيْهِ الْمَاءُ وَبَوْلُ الْجَارِيَةِ يُغْسَلُ وَقَالَ بَهْزٌ غُسْلًا حَدَّثَنَا عَفَّانُ قَالَ حَدَّثَنَا حَمَّادٌ قَالَ حُمَيْدٌ كَانَ عَطَاءٌ يَرْوِيهِ عَنْ أَبِي عِيَاضٍ عَنْ لُبَابَةَ
