Many claims are made for the miraculous nature of the Qur'an.
Some claims are made for the miraculous Scientific Facts contained within.
Some claims are made for the miraculous Mathematical Patterns contained within.
As far as I'm concerned these things don't constitute a miracle, let me explain why.
Satan (The Devil) has been around for longer than mankind, this has been more than enough time for him to learn all the scientific facts that we know today.
Satan has been around for longer than mankind, this has been more than enough time for him to learn the most advanced mathematics that we know today - Maybe he even knows Pi (3.141592653........).
Satan has had more than enough time to learn all the languages in the world.
As far as I'm concerned the only miracle that a Scripture can contain is the miracle of prophecy.
By the way, I don't think Satan wrote the Qur'an.....
I think he could have made a more convincing case.
