Surah An-Noor Verse 27 - English Translation by Safi Kaskas
Surah An-Noorيَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُواْ لَا تَدۡخُلُواْ بُيُوتًا غَيۡرَ بُيُوتِكُمۡ حَتَّىٰ تَسۡتَأۡنِسُواْ وَتُسَلِّمُواْ عَلَىٰٓ أَهۡلِهَاۚ ذَٰلِكُمۡ خَيۡرٞ لَّكُمۡ لَعَلَّكُمۡ تَذَكَّرُونَ
Believers do not enter houses other than your own until you have asked permission to do so and greeted their residents. That is best for you, so that you will be reminded [of each other's rights]
