One of the Great Miracles [74:35] 7+4+3+5=19 The Quran is characterized by a unique phenomenon never found in any human authored book. Every element of the Quran is mathematically composed — the suras, the verses, the words, the number of certain letters, the number of words from the same root, the number and variety of divine names, the unique spelling of certain words, the absence or deliberate alteration of certain letters within certain words, and many other elements of the Quran besides its content. There are two major facets of the Quran's mathematical system: (1) The mathematical literary composition, and (2) The mathematical structure involving the numbers of suras and verses. Because of this comprehensive mathematical coding, the slightest distortion of the Quran's text or physical arrangement is immediately exposed. Simple to Understand Impossible to Imitate For the first time in history we have a scripture with built-in proof of divine authorship — a superhuman mathematical compositionNineteen is the common denominator throughout the Quran's mathematical system. This phenomenon alone suffices as incontrovertible proof that the Quran is God's message to the world. No human being(s) could have kept track of 2698 occurrences of the word “God,” and the numbers of verses where they occur. This is especially impossible in view of (1) the age of ignorance during which the Quran was revealed, and (2) the fact that the suras and verses were widely separated in time and place of revelation. .
