Is Quran the proof of God?

[downbeatplumb]

And clearly you didn't bother to read the rules.   
Miracles!   As somebody else posted, they MIGHT be worth looking at if all of the modern "miracles" mentioned were actually in the original text.  Otherwise, all you have is someone manipulating letters and numbers in a book.  You can do that with ANY book.  You can find the same "miracles" in a Harry Potter book, a cookbook, or a newspaper.

I'm not saying you are wrong, but can you show examples of other books having a lot of coincidences like Quran does? You can read some of those there though I can't testify to all that's there: http://www.miraclesofthequran.com/mathem...index.html 

(haven't checked all, but all the ones I have checked were true)

I want to understand this thing. What is the probability etc.

Why yes the bible is full of them.

As is every book of sufficient length. Look up numerology and Moby Dick or Harry Potter.
