(Annoor) 24 : 28
فَإِنْ لَمْ تَجِدُوا فِيهَا أَحَدًا فَلَا تَدْخُلُوهَا حَتَّىٰ يُؤْذَنَ لَكُمْ ۖ وَإِنْ قِيلَ لَكُمُ ارْجِعُوا فَارْجِعُوا ۖ هُوَ أَزْكَىٰ لَكُمْ ۚ وَاللَّهُ بِمَا تَعْمَلُونَ عَلِيمٌ
And if you don’t find anyone therein, you don’t enter there till you are given permission; and if it is said to you: "Go back," then you go back, it is purer for you, and Allah is the Knowing of whatever you are doing.
