Blogger Comment:
One of the strong proofs of the Quran is the number of people who read it, recite it, memorize it or translat it. See many translations above to one single verse in the Quran. The verse have few words with strong meaning: To those who believe in other Gods than that of the Quran simply bring proofs. The proof of God in the quran is what in the Quran and what it is revealed from the true communications before between God and humans that mentioned in the Quran. Those people most of them do not know the truth (they did not try to know or know and blunt their own knowledge or anything to block themselves from the truth) so they are stubborn.
If your read the verse in Arabic it is fewer in words than all of our translations and clear in conveying the message with glorious and authortative speech.
