Conquest of Mecca
27- Truly God fulfilled His messenger’s vision. You will enter the Restricted Mosque in security, if God wills. You will cut your hair or shorten it, you will not have any fear. Since He knew what you did not know, He has preceded this with an immediate victory.
Another prophecy similar to the victory of the Romans was the realization of the premonitory dream of Muhammad in which he saw himself entering the Restricted Mosque (the mosque which surrounded the Kaaba of Mecca, the place of pilgrimage). Just to remind you, the Prophet and his followers had been expelled from Mecca and the Meccans were superior both in military power and equipment.
Many prophets died before they could establish sovereignty in the land in which they spread their religion. Had there been no such tidings, Muhammad could not possibly have foreseen that the day would come when he would be in a position to conquer Mecca.
All Quranic verses reflect poise, confidence and self-reliance. There is nothing in them to suggest the ambivalence, vacillation and equivocation that one can encounter in other works whose authors were human beings.
89- …We have sent down to you a Book explaining all things, a guide, a mercy and glad tidings for those who submit.
