Assalamualaikum,

The Quran mentions number 19, so therefore is must be important. The Quran has 6236 verses. In Surah Shu'ara the opening verse is طسم (Taw Sin Mim). This verse has no meaning in arabic but the verse after this verse should explain everything. So the verse after is تِلْكَ اٰيٰتُ الْكِتٰبِ الْمُبِيْنِ which means "These are the verses of the Clear Book." The second verse is referring to the previous verse Taw Sin Mim, so this means that the first verse is equal to every verse in the Quran. Since there are 6236 verses in the Quran and the Quran told us that number 19 is important, we will see how many verses are in the Quran in Base-19 (In Base-19, the number 10 has to be equal to 19 in Base-10. So the numbers in Base 19 are 1,2,3,4,5,6,7,8,9,A,B,C,D,E,F,G,H,I, and 10. If you count all numbers of Base 19, you'll see that 10 in Base 19 is equal to 19 in Base 10). 6236 is equal to H54 in Base 19 (I used a base calculator). Now let's go back to the verse طسم. Let's see how many times each letter of the verse is repeated in other verses that have no meaning in arabic throughout the Quran in Base 19 form. م appears H (17) times, س appears 5 times, and ط appears 4 times.

ط س م

H 5 4

You see! H54 is the amount of verses in the Quran and is the quantity of each letter in Taw Sin Mim! Sorry I worded this so badly.

Assalamualaikum
