سورة Al-Fath ( The Victory ) - الآية 27

Indeed Allah shall fulfil the true vision which He showed to His Messenger (SAW) [i.e. the Prophet SAW saw a dream that he has entered Makkah along with his companions, having their (head) hair shaved and cut short] in very truth. Certainly, you shall enter Al-Masjid-al-Haram; if Allah wills, secure, (some) having your heads shaved, and (some) having your head hair cut short, having no fear. He knew what you knew not, and He granted besides that a near victory.
