28فَإِن لَم تَجِدوا فيها أَحَدًا فَلا تَدخُلوها حَتّىٰ يُؤذَنَ لَكُم ۖ وَإِن قيلَ لَكُمُ ارجِعوا فَارجِعوا ۖ هُوَ أَزكىٰ لَكُم ۚ وَاللَّهُ بِما تَعمَلونَ عَليمٌZafar AnsariThen, if you do not find anyone therein, do not enter until you have been given permission, and if you are told to go back, you should go back. This is a purer way for you; and Allah has full knowledge of what you do.
