hence if you find no one within do not enter it until you are given leave and if you are told turn back then turn back. this will be most conducive to your purity and god has full knowledge of all that you do.
فإن لم تجدوا فيها أحدا فلا تدخلوها حتى يؤذن لكم وإن قيل لكم ارجعوا فارجعوا هو أزكى لكم والله بما تعملون عليم
