He narrated the tradition to the same effect, but he did not mention the words "until the age of eating". This version adds: Qatadah said: This is valid until the time they do not eat food; when they begin to eat, their urine should be washed.
أَنَّ النَّبِيَّ ﷺ قَالَ فَذَكَرَ مَعْنَاهُ وَلَمْ يَذْكُرْ مَا لَمْ يَطْعَمْ زَادَ قَالَ قَتَادَةُ هَذَا مَا لَمْ يَطْعَمَا الطَّعَامَ فَإِذَا طَعِمَا غُسِلاَ جَمِيعًا
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
Ibn Abul-Aswad from his father - that ‘Ali ؓ said: The Messenger of Allah ﷺ said: “The urine of a nursing boy may be sprinkled with water and the urine of a nursing girl is to be washed.” Qatadah said: This is if the infant is not yet eating solid food; if the infant is eating solid food, it is to be washed in both Cases.
أَنَّ رَسُولَ اللهِ ﷺ قَالَ بَوْلُ الْغُلامِ الرَّضِيعِ يُنْضَحُ وَبَوْلُ الْجَارِيَةِ يُغْسَلُ قَالَ قَتَادَةُ وَهَذَا مَا لَمْ يَطْعَمَا الطَّعَامَ فَإِذَا طَعِمَا الطَّعَامَ غُسِلا جَمِيعًا قَالَ عَبْدُ اللهِ وَلَمْ يَذْكُرْ أَبُو خَيْثَمَةَ فِي حَدِيثِهِ قَوْلَ قَتَادَةَ
ʿSprinkle water on the urine of a boy and wash the urine of a girlʿ Qatadah said: This is so long as they are not eating solid food; if they are eating solid food, both are to be washed.
أَنَّ رَسُولَ اللهِ ﷺ قَالَ فِي الرَّضِيعِ يُنْضَحُ بَوْلُ الْغُلامِ وَيُغْسَلُ بَوْلُ الْجَارِيَةِ قَالَ قَتَادَةُ وَهَذَا مَا لَمْ يَطْعَمَا الطَّعَامَ فَإِذَا طَعِمَا غُسِلا جَمِيعًا
