but if you do not find anyone in them do not enter them until you are given permission. and if you are told turn back then do turn back. that is more decent for you. allah knows best what you do.
فإن لم تجدوا فيها أحدا فلا تدخلوها حتى يؤذن لكم وإن قيل لكم ارجعوا فارجعوا هو أزكى لكم والله بما تعملون عليم
