The Messenger of Allah ﷺ said: ʿThe urine of a boy is to be sprinkled with water and the urine of a girl is to be washed.ʿ Qatadah said: That is if they are not yet eating solid food; if they are eating solid food then their urine is to be washed in both cases.
قَالَ رَسُولُ اللهِ ﷺ بَوْلُ الْغُلامِ يُنْضَحُ عَلَيْهِ وَبَوْلُ الْجَارِيَةِ يُغْسَلُ قَالَ قَتَادَةُ هَذَا مَا لَمْ يَطْعَمَا فَإِذَا طَعِمَا غُسِلَ بَوْلُهُمَا
the Messenger of Allah said, about urine of a male child that suckles: "The urine of the boy is sprinkled, and the girl's urine is washed." Qatadah (one of the narrators) said: "This is so, as long as they do not eat, when they eat, then both of them are washed."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ فِي بَوْلِ الْغُلاَمِ الرَّضِيعِ يُنْضَحُ بَوْلُ الْغُلاَمِ وَيُغْسَلُ بَوْلُ الْجَارِيَةِ قَالَ قَتَادَةُ وَهَذَا مَا لَمْ يَطْعَمَا فَإِذَا طَعِمَا غُسِلاَ جَمِيعًا
ʿSprinkle water on the urine of a boy and wash the urine of a girl.ʿ Qatadah said: This applies so long as they are not eating solid food; if they are eating solid food, then it is to be washed in both cases.
أَنَّ رَسُولَ اللهِ ﷺ قَالَ فِي الرَّضِيعِ يُنْضَحُ بَوْلُ الْغُلامِ وَيُغْسَلُ بَوْلُ الْجَارِيَةِ قَالَ قَتَادَةُ وَهَذَا مَا لَمْ يَطْعَمَا الطَّعَامَ فَإِذَا طَعِمَا غُسِلا جَمِيعًا
