Surah An-Nur, Verse 58

يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لِيَسۡتَـٔۡذِنكُمُ ٱلَّذِينَ مَلَكَتۡ أَيۡمَٰنُكُمۡ وَٱلَّذِينَ لَمۡ يَبۡلُغُواْ ٱلۡحُلُمَ مِنكُمۡ ثَلَٰثَ مَرَّٰتٖۚ مِّن قَبۡلِ صَلَوٰةِ ٱلۡفَجۡرِ وَحِينَ تَضَعُونَ ثِيَابَكُم مِّنَ ٱلظَّهِيرَةِ وَمِنۢ بَعۡدِ صَلَوٰةِ ٱلۡعِشَآءِۚ ثَلَٰثُ عَوۡرَٰتٖ لَّكُمۡۚ لَيۡسَ عَلَيۡكُمۡ وَلَا عَلَيۡهِمۡ جُنَاحُۢ بَعۡدَهُنَّۚ طَوَّٰفُونَ عَلَيۡكُم بَعۡضُكُمۡ عَلَىٰ بَعۡضٖۚ كَذَٰلِكَ يُبَيِّنُ ٱللَّهُ لَكُمُ ٱلۡأٓيَٰتِۗ وَٱللَّهُ عَلِيمٌ حَكِيمٞ٥٨

O you who have believed, let those whom your right hands possess and those who have not [yet] reached puberty among you ask permission of you [before entering] at three times: before the dawn prayer and when you put aside your clothing [for rest] at noon and after the night prayer. [These are] three times of privacy for you. There is no blame upon you nor upon them beyond these [periods], for they continually circulate among you - some of you, among others. Thus does Allāh make clear to you the verses [i.e., His ordinances]; and Allāh is Knowing and Wise.
