Numeral system that proves the Quran was preserved.
The Quran mentions number 19 and insists on counting them so we looked at the Quran from this perspective and found that the Quran is coded with base-19.
Some chapters start with letters that have no meaning in Arabic:
[Quran 26.1-4] Ta, Seen, Meem, these are verses of the clarifying book. Maybe you are frustrated that they don’t believe. If We wish We can send down from heaven a sign their necks remain for it subdued.
“Ta, Seen, Meem, these are verses of the clarifying book” this verse is referring to the three letters Ta, Seen, Meem. We know that the Quran has 6236 verses however this is in base-10. In base-19 the Quran has H54 verses. 1400 years ago the Arabs knew and used base-10 correctly however nobody knew base-19 at that time.
When we replace those letters by their count we get the number of verses in the Quran in base-19 H54.
These are the letters and how many times they appear in those chapters:
And this is their count in base-19:
Ta, Seen, Meem turned out to be H54 in base-19. This is 6236 in base-10 (17x19x19 + 5×19 + 4) the exact number of verses in the Quran.
If a single verse was added or removed from anywhere in the entire Quran this code would have been broken.
This chapter starts with the exact number of verses in base-19 then the very next verse “these are verses of the clarifying book” and talks about a sign for disbelievers. This sign for disbelievers turned out to be base-19.
