The Quran has no author, and no group or individual in Arabia has ever claimed to have written it, nor has any group or individual recited, taught, and explained the Quran before the Prophet Mohammad . Any historian, Muslim or non-Muslim would argue that the only possible source of the Quran could be the Prophet Mohammad , the man responsible for reciting, teaching, and explaining it to the people of Arabia. This has led some thinkers and Orientalists to conclude that the Prophet , must have written the Quran.
Those who believe that Prophet Muhammad , was the author of the Quran are absolutely wrong. However, merely saying that they are incorrect is not enough, without providing proofs. If we contemplate the nature of this glorious book (the Quran) and the capabilities of the Prophet , we will realize that these claims are illogical and groundless.
First, Prophet Muhammad , was unlettered. How can an illiterate person come up with such a rich, intellectual, and inspiring text that gained acceptance not only in Arabia, but also throughout the world Prophet Mohammad , never went to school! No one taught him. He had no teacher of any kind in any specific subject. How could he acquire the knowledge of Science, astronomy, oceanography, etc. that is contained in the Quran? (For example, the mention of ocean currents, stars, earth, moon, sun and their fixed paths in Chapter Ar-Rahmaan; and many other scientific statements that are found in the Quran, that cannot be stated in this short article)
