The Quran turned out to have a unique signature:
The count of chapters (Suras) in the Quran is a multiple of 19.
The sum of chapters’ numbers in the Quran is a multiple of 19.
The sum of all digits mentioned in the Quran is a multiple of 19.
The count of the word “Allah” in all the Quran is a multiple of 19.
The sum of all verse numbers (Ayat numbers) in which the word “Allah” appears is a multiple of 19.
Some chapters start with letters that have no meaning at all. When we add the number of occurrences of those letters in their chapters we always get a multiple of 19… So if anyone changed a single word containing those letters in the Quran the signature would have been broken.
God says that He assigned 19 angels to guard Hell, and He made their count “19” so that believers shall increase their faith.
(In the Christian Bible Jesus insists that the only sign we should verify is him being in the grave for three days and three nights (Matthew 12:38-40). So we are checking: He was crucified on Friday afternoon, the day before the Sabbath (Mark 15:42) and then he was resurrected on Sunday morning (Mark 16:9). Between Friday afternoon and Sunday morning there is 36 hours. Can anyone fit within those 36 hours three days and three nights?)
Allah says in the Quran:
