Quran Miracle: Allah Gives Exact Words Hadith Supporters Say

The creator of the universe, our master Allah already gave verses in which he gives us glimpse of what hadith supporters would say in the future to those who follow only Quran.

25:32 And those who disbelieve say, "Why was the Qur'an not revealed to him all at once?" Thus [it is] that We may strengthen thereby your heart. And We have spaced it distinctly.

Now watch what a sectarian says:

It is also important to understand that The Holy Prophet (S.A.W.) spent 23 years slowly revealing the Qur'an bit by bit. Why 23 years? If the Qur'an is enough, then why 23 years of revelation and wars. Why did the book not fall from the sky and a random person read it and convert to a new religion?

Here is another one.

So according to average Muslim, if Quran was complete it would have been revealed all at once instead of taking 23 years.
