Problem with the Qur'an is it's extremely ambiguous.
And many muslims claim that you can't get the true meaning from an English translation.
Many say that you have to read it in the original Arabic.
Another problem.
Arabic is a very difficult language, Second only to Chinese.
Many Arabs call Arabic the language of Saad, as the letter Saad is one of the most difficult for non-Arabs to vocalize.
Mant Arabs claim that non-Arabs aren't able to pronounce this letter.
If I were to call a book miraculous I would like it to have the following criteria;
1. It should be easily translated into any language without ambiguity.
2. It should be easily understood by everyone.
3. It should be easily pronounced by everyone.
4. It should be available to everyone.
5. Its truth should be measured by the interest it generates.
It would be truly a miracle if it was revealed in One Universal Language that could be understood by anyone who reads it. A language unspoken in the world, but easily understood when read.
