if ye find no one in the house enter not until permission is given to you if ye are asked to go back go back that makes for greater purity for yourselves and allah knows well all that ye do.
فإن لم تجدوا فيها أحدا فلا تدخلوها حتى يؤذن لكم وإن قيل لكم ارجعوا فارجعوا هو أزكى لكم والله بما تعملون عليم
