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.
The Saheeh International Quran Translation
فَإِن لَّمْ تَجِدُوا۟ فِيهَآ أَحَدًا فَلَا تَدْخُلُوهَا حَتَّىٰ يُؤْذَنَ لَكُمْ وَإِن قِيلَ لَكُمُ ٱرْجِعُوا۟ فَٱرْجِعُوا۟ هُوَ أَزْكَىٰ لَكُمْ وَٱللَّهُ بِمَا تَعْمَلُونَ عَلِيمٌAnd 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.
