The words of Allah, "Once your children have reached puberty" (24:57) Al-Adab Al-Mufrad 1058
Arabic hadith text
حَدَّثَنَا مَطَرُ بْنُ الْفَضْلِ، قَالَ: حَدَّثَنَا يَزِيدُ بْنُ هَارُونَ، عَنْ هِشَامٍ الدَّسْتُوَائِيِّ، عَنْ يَحْيَى بْنِ أَبِي كَثِيرٍ، عَنْ نَافِعٍ، عَنِ ابْنِ عُمَرَ، أَنَّهُ كَانَ إِذَا بَلَغَ بَعْضُ وَلَدِهِ الْحُلُمَ عَزَلَهُ، فَلَمْ يَدْخُلْ عَلَيْهِ إِلا بِإِذْنٍ.
Translation
Ibn 'Umar reported that when his children had reached puberty and he had withdrawn to his room, none of them entered where he was except with his permission.
