An-Nur - 24:59

وَإِذَا بَلَغَ الْأَطْفَالُ مِنكُمُ الْحُلُمَ فَلْيَسْتَأْذِنُوا كَمَا اسْتَأْذَنَ الَّذِينَ مِن قَبْلِهِمْ كَذَلِكَ يُبَيِّنُ اللَّهُ لَكُمْ آيَاتِهِ وَاللَّهُ عَلِيمٌ حَكِيمٌ
[24:59]
And when the children among you have attained to puberty, let them seek permission as those before them sought permission; thus does Allah make clear to you His communications, and Allah is knowing, Wise.
But when the children among you come of age, let them (also) ask for permission, as do those senior to them (in age): Thus does Allah make clear His Signs to you: for Allah is full of knowledge and wisdom.
And when the children among you come to puberty then let them ask leave even as those before them used to ask it. Thus Allah maketh clear His revelations for you. Allah is Knower, Wise.
