Even the non-Muslim scholars admit to the authenticity of the Quran. For example, Laura Vaccia Vaglieri, professor at the University of Naples, has the following to say:

"The heavenly book of Islam is miraculous and inimitable. Its style is totally unprecedented in Arabic literature, and its peculiar impact on the spirit of the human being derives from its special and superior characteristics. How is it possible that such a book should be the work of Muhammad, an Arab who had never studied? We find in this book a treasury of knowledge beyond the capacity of the greatest philosophers and statesman, and for this reason it is also impossible to regard the Quran as the work of an educated person".

Smith writes in his book: Muhammad and Islam:

"I boldly assert that one day the loftiest of human philosophers and the most veracious principles of Christianity will confess and bear witness that the Quran is the Word of God. An unlettered and unlearned Prophet was chosen by God to bring the Quran to Mankind, a book that has in the course of history produced thousands of other books and treatises, brought libraries into being and filled them with books, and placed before mankind laws and philosophies and educational, intellectual and ideological systems.

"He arose in an environment where there was no trace of learning and civilization. In the whole of Madina, there were only eleven people who knew how to read and write, and in all the branches of Quraysh, in Mecca and its environs, not more than seventeen people were literate.

"The teachings of the Quran, which mentions knowledge and the pen in its opening verses, brought about a tremendous transformation. Islam proclaimed study to be a religious duty, and made the black ink of scribe and the scholar to be superior to the red blood of the martyr.

"Thanks to the teachings of the Quran and its emphasis on the cultivation of knowledge, countless scholars made their appearance and wrote innumerable books. Different scientific disciplines were derived from the Quran and spread across the world by Muslim thinkers. The world was illuminated with the lights of the Quran and the culture of Islam."

Numerous other non-Muslim Scholars have attested to the fact that Quran is the word of God. However, we shall not mention them for the sake of brevity.
