Surah An-Noor Verse 28 - English Translation by Ahmed Ali
Surah An-Noorفَإِن لَّمۡ تَجِدُواْ فِيهَآ أَحَدٗا فَلَا تَدۡخُلُوهَا حَتَّىٰ يُؤۡذَنَ لَكُمۡۖ وَإِن قِيلَ لَكُمُ ٱرۡجِعُواْ فَٱرۡجِعُواْۖ هُوَ أَزۡكَىٰ لَكُمۡۚ وَٱللَّهُ بِمَا تَعۡمَلُونَ عَلِيمٞ
If you find that no one is in, then do not enter unless you have received permission. If you are asked to go away, turn back. That is proper for you. God is aware of what you do
