This expansive book provides unique insights into the holy text's immaculate preservation, as well as exploring many of the accusations leveled against it. The reception of divine revelations, Prophet Muhammad's role in disseminating and compiling these verses, and the setting of the text's final external shape are scientifically examined alongside such topics as the origins of Arabic, the so-called Mushaf of Ibn Masud, and the strict methodology employed in assembling textual fragments. By way of comparison, the author investigates the histories of the Old and New Testaments, relying entirely on Judeo-Christian sources, and uncovers a startling range of alterations in the biblical Scriptures. Using this as a springboard, he illustrates convincingly that Western research into Islam's Holy Book is motivated by more than mere curiosity, and has no scientific bearing on the Quran's integrity. This monumental effort, a scholarly work composed in an impassioned tone, provides a welcome foundation for sincere study at a time when assailing the Quran has become all too common.
