This is a classical sample of deceptive literature common in the last 50 years. In between the line, the author is introducing his non-muslim movement Khaliffite by confusing the reader by his so called mathematical miracle of the Quran. By the way, I would like to add that his translation of the Quran is completely errounous. In his translation, he deleted many verses, changed and added others just for the sake to preserve his non-sense errounous mathematical theory. Even his theory, even a primary school student can demontrate how wrong it is. This is because the author himself strictly speaking is not a muslim and belonged to an anti-islamic sect.
