This book contains numerous debates on the prophetic numerical system embedded ni the Quran. Edip Yüksel responds and refutes critics and skeptics, such as: Abu Ameenah Bilal Philips: Sunni scholar Carl Sagan: astronomer, astrophysicist, cosmologist, and skeptic author Daniel Abdurrahman Lomax: Sunni computer engineer Ayman Mutaakher: anonymous Sunni critic James (Amazing) Randi: founder of Randi Foundation, a skeptic activist Michael Shermer: editor and publisher of the Skeptic Magazine, author, columnist The miraculous function of the number 19 prophesized in Chapter 74 was unveiled in 1974 through a computerized analysis of the Quran. Though, in retrospect, the implication of 19 in Chapter 74 traditionally called Hidden One, were obvious, it remained a secret for 1406 (19x74) lunar years after the revelation of the Quran. Ironically, the first words of the Chapter 74, The Hidden One, was revealing, yet the code was a divinely guarded gift allocated to the computer generation; they were the one who would need and appreciate it the most. As we have demonstrated in various books, hundreds of simple and complex algorithms, we witness the depth and breath of mathematical manipulation of Arabic, an arbitrary human language, to be profound and extraordinary. This is the fulfillment of a Quranic challenge (17:88). While the meaning of the Quranic text and its literal excellence was kept, all its units, from chapters, verses, words to its letters were also assigned universally recognizable roles in creation of mathematical patterns. Since its discovery, the number 19 of the Quran and the Bible has increased the appreciation of many of those who acknowledge the truth, has removed doubts in the minds of many People of the Book, and has caused discord, controversy and chaos among those who have traded the Quran with men-made sectarian teachings. This is indeed a fulfillment of a Quranic prophecy (74:30-31). 14.The improbability and impossibility of the numerical structure of the Quran being produced by a medieval Arab genius becomes evident when we consider the following factors: -It includes simple elements of the Quran and goes deeper to an interlocking system of complex numerical patterns and relationships. -It involves not only frequencies of letters and words but also the numerical values of letters. -It involves not only an intricate numerical pattern but also a huge set of data consisting of units with multiple functions, such as letters that are also digits, words that are also numbers. -The nemeroliteral aspect of the Quran were not known by the adherents of the Quran until late 1960s and especially, 1974. -The literary aspect of the Quran has received praises from many literary giants throughout centuries. -The scientific accuracy of Quranic statements on various fields has been immaculate. -Muhammad was one of the busiest and greatest social and political reformists in human history. -The timing of the discovery of the code is precise and prophetic. -A series of prophetic events regarding the code has been fulfilled.
