An-Nur 24:28

فَإِن لَّمْ تَجِدُوا۟ فِيهَآ أَحَدًا فَلَا تَدْخُلُوهَا حَتَّىٰ يُؤْذَنَ لَكُمْ ۖ وَإِن قِيلَ لَكُمُ ٱرْجِعُوا۟ فَٱرْجِعُوا۟ ۖ هُوَ أَزْكَىٰ لَكُمْ ۚ وَٱللَّهُ بِمَا تَعْمَلُونَ عَلِيمٌ

Fa-in lam tajidū fīhā aḥadan falā tadkhulūhā ḥattā yu'dhana lakum wa-in qīla lakumu ir'jiʿū fa-ir'jiʿū huwa azkā lakum wal-lahu bimā taʿmalūna ʿalīmun

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 Allāh is Knowing of what you do.
