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
If you find no one in, do not enter unless you have been given permission to do so. If you are told, ‘Go away’, then do so- that is more proper for you. God knows well what you do.
And if you find no one therein, still, enter not until permission has been given. And if you are asked to go back, go back, for it is purer for you. And Allâh is All-Knower of what you do.
