Surah An-Noor Verse 27 - English Translation by Aisha Bewley
Surah An-Noorيَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لَا تَدۡخُلُواْ بُيُوتًا غَيۡرَ بُيُوتِكُمۡ حَتَّىٰ تَسۡتَأۡنِسُواْ وَتُسَلِّمُواْ عَلَىٰٓ أَهۡلِهَاۚ ذَٰلِكُمۡ خَيۡرٞ لَّكُمۡ لَعَلَّكُمۡ تَذَكَّرُونَ
You who have iman! do not enter houses other than your own until you have asked permission and greeted their inhabitants. That is better for you, so that hopefully you will pay heed
