Of these prophecies are the following...
Of these prophecies are the following: “Certainly We have revealed the Reminder (the Qur'an), and we shall preserve it.” 15:9 This verse informs us that the Qur'an shall not perish. It shall not disappear from this world, and it will last and continue forever. This prediction was actually the opposite of what was humanly expected. The Qur'an was introduced by a prophet who was unschooled and unable to read or write. He introduced it in a language of an illiterate nation.
The Arabs at the time of the Prophet did not have a hundred readers in a million. In addition to this, the overwhelming majority of that nation was standing against the Prophet and his book, and so was the rest of the world. Under these circumstances, such a book was expected to perish and disappear. The chances of its continuity for so many generations were very slim. The following verse explains: “It (the Qur'an) is an invincible book.
Falsehood does not invade it neither from before it nor from behind it, a revelation from a Mighty, Praised One.” 41:41-42 This verse informs the world that the Qur'an will not be interpolated by words that had been said before the time of its revelation nor by words that will be said after the time of its revelation. It will be pure and will continue so forever. This, also, was a prediction contrary to what was humanly expected.
A book, introduced under the circumstances which we advanced, could not be humanly expected to stay pure without any interpolation. There was no printing-machine at the time of revelation, nor such a machine was invented until several centuries after Muhammad. History shows us that no holy book had remained pure without interpolation. The holy books had undergone many changes in many centuries. The Qur'an was expected not to be exceptional. The two prophecies had been entirely fulfilled.
The fulfillment of the first is self-evident: The Holy Qur'an did not perish. It lived and remains a highly living book. Actually the life of the Qur'an is so rich that it may be the most recited book in the world. Every Muslim is expected to pray five times a day, and each prayer includes a recital from the Holy Qur'an. Hundreds of millions of Muslims perform their daily prayers, and hundreds of millions of times the Qur'an is daily recited.
The fulfillment of the second prophecy is quite obvious. The Holy Qur'an remained unchanged. No human word was inserted into it.
