فَإِن لَّمۡ تَجِدُواْ فِيهَآ أَحَدٗا فَلَا تَدۡخُلُوهَا حَتَّىٰ يُؤۡذَنَ لَكُمۡۖ وَإِن قِيلَ لَكُمُ ٱرۡجِعُواْ فَٱرۡجِعُواْۖ هُوَ أَزۡكَىٰ لَكُمۡۚ وَٱللَّهُ بِمَا تَعۡمَلُونَ عَلِيمٞ
Fa il lam tajidoo feehaaa ahadan falaa tadkhuloohaa hattaa yu'zana lakum wa in qeela lakumurji'oo farji'oo huwa azkaa lakum; wallaahu bimaa ta'maloona 'Aleem
English Translation
And if you do not find anyone therein, do not enter them until permission has been given you. And if it is said to you, "Go back," then go back; it is purer for you. And Allah is Knowing of what you do
