"And if you are in doubt as to what We [Allah] have revealed then produce a Surah (chapter) like there unto" ( the Holy Quran - Surah Al-Baqarah 2:23)
This was the challenge put forth by Allah in the Quran 1400 years ago. As of yet, none has or will ever come close to meeting this challenge. Hence, as a result, multitudes throughout the centuries have believed and continue to believe in the Quran as a revelation beyond any human capacity. Modern scientists, for instance, have been amazed by the accuracy of scientific information presented in the Quran. Here are just a few examples:
In his book of embryology-'The Developing Human' [W.B. Saunders Publishing, 1982], Dr. Keith Moore added a whole chapter to discuss the scientific accuracy of the Quranic discussion of this science.
Another eminent scientist, Dr. Maurice Bucaille wrote in his book-'The Bible, the Quran and Science':
"I could not find a single error in the Quran, if a man was the author of the Quran how could he have written facts in the 7th century A.D. that today are shown to be in keeping with modern scientific knowledge" - Dr. Maurice Bucaille
