Al-Fath 48:27 لقد صدق الله رسوله الرويا بالحق لتدخلن المسجد الحرام ان شاء الله امنين محلقين رءوسكم ومقصرين لا تخافون فعلم ما لم تعلموا فجعل من دون ذالك فتحا قريبا ٢٧

Indeed, Allah has made true to His Messenger the dream (shown) with truth: You will definitely enter the Sacred Mosque inshā’allāh (if Allah wills,) peacefully, with your heads shaved, and your hairs cut short, having no fear. So He knew what you did not know, and He assigned before that a victory, near at hand.
