Notification of encryption has been found in the Qur’an. Very clearly the number 7 and 19 is emphasized in verses. In addition, the functions of the number 19 are detailed in the Qur’an.

15-Al-Hijr – verse 87

وَلَقَدْ اٰتَيْنَاكَ سَبْعًا مِنَ الْمَثَانٖى وَالْقُرْاٰنَ الْعَظٖيمَ

15-Al-Hijr – verse 87: And We have certainly given you, [O Muhammad], seven of the often repeated [verses] and the great Qur’an

74-Al-Muddaththir – verse 30

عَلَيْهَا تِسْعَةَ عَشَرَ

https://quran.com/74/30 – SAHIH INTERNATIONAL

74-Al-Muddaththir – verse 30: Over it are nineteen [angels].

There are mentioned to another numbers in the Qur’an in excluding from 19. But almost all of these numbers were used to characterize a name. Four months, seven heavens, a thousand months like this… But, after being highlighted at 30th verse, at 31th verse saying “their number”, the functions of number 19 is explained.

74-Al-Muddaththir – verse 31: And We have not made the keepers of the Fire except angels. And We have not made their number except as a trial for those who disbelieve – that those who were given the Scripture will be convinced and those who have believed will increase in faith and those who were given the Scripture and the believers will not doubt and that those in whose hearts is hypocrisy and the disbelievers will say, “What does Allah intend by this as an example?” Thus does Allah leave astray whom He wills and guides whom He wills. And none knows the soldiers of your Lord except Him. And mention of the Fire is not but a reminder to humanity.

Here, let’s pay attention and catch the gist of the subject. What is mentioned in the verse, which is used as a means of trial for infidels. Is it the angels themselves? No, it’s number, it’s number 19. The number is mentioned in the verse and the functionality of the number is explained. It is clearly stated in the verse of the Qur’an, the number 19, which is the test for the unbelievers, has been made. Other functions of the number 19 mentioned in the verse of the Qur’an are as follows.

These functions are:

1- A strife for the unbelievers (a plague, an element that is against them).

2- The ability to persuade the given Book (Jews, Christians)

3- Make sure that believers believe with a certain knowledge

4- Destroy the doubts of believers and those given a book

5- Creating a situation in which people with heart disease cannot understand and underestimate this example.

Observation results:

The Qur’an index is different from the order of descent. Historical sources tell us that the order of descent is different. This difference is remarkable. Why is there a difference? As a result of our observations, we discovered that there was a profound meaning in the different order of the Mushaf index. In the Mushaf index there is a very clearly recognized mathematical structure.

Even and Odd Symmetry System: In the Qur’an index, the Even and Odd symmetry that we observe in the number set of surah numbers and the number of verses in the Qur’an is taken into consideration by swearing on Even and Odd in verse 89: 3 of the Qur’an.

89-Al-Fajr – verse 3

وَالشَّفْعِ وَالْوَتْرِ

https://quran.com/89/3-5 – SAHIH INTERNATIONAL

89-Al-Fajr – verse 3:  And [by] the even [number] and the odd,

In English, it is obvious that even and odd expressions are used for numbers. Because in English also has words like Double, Single which can be used for this subject too. Among these words, Even and Odd are preferred for numbers. When Even Numbers are expressed in English, the words “Even Numbers” are more appropriate instead of “Double numbers”.

The symmetric structure of the Even and Odd symmetry itself, the connections to the numerical coding system 7 and 19, has shown that this structure contains a numerical coding and is extraordinary. We see and understand that the Mushaf index of the Quran is original with Even and Odd symmetry system.

I will share the details in the following sections;

• Pointed out on the number 7 in the verse 87 of the Surah 15 and details of numerical coding
• Pointed out on the number 19 in verse 30 of Surah 74 and Qur’an declaration in verse 31, the functions of number 19
• The Numerical codings in 1.Al-Fatihah surah and in 96.Al-Alaq surah

   (19th surah from end of index and has 19 verses, first descending surah)

Points indicated above have helped us understand how the Numerical Coding System is.
In all dataset we’re considering with in the Qur’an, the numbers of repetition of the word “Allah” in the Qur’an verses and in the verses which are the multiples of 19 and 19, the numbers of the words of Name, Allah, Rahman and Rahim, which are the words of Basmalah, the number of letters of Hurufu Mukatta in the relevant surahs, the numbers in our other observations, all the things may also be a coincidence that are exactly divided by 19. However, the possibility that these correlations are deliberately regulated should be seriously taken into account if interrelationships are creating new ones and adding new ones.  Please see Ha-Mim group coding. I observed that the mathematical structure I obtained was perfect, extraordinary and perfectly protected the Qur’an. See the related sections for details.

At this point, I would like to address theologians; If someone brings you by typing an Arabic text “Your Qur’an challenges that people cannot bring a similar surah. Look, I have written and brought one, this surah is like surahs in the Qur’an, how will you prove to me that it is not like surah in the Qur’an?” and asks, how will they answer, I wonder, on what bases they will argue that the text is not like the surahs in the Qur’an. I want to know and I’m waiting for their explanation. The claim of the Quran is the claim of the whole Islamic world, therefore the Islamic world should clearly put forward the criteria for the claim that “people cannot bring a similar one of the Quran” and scientifically demonstrate that these criteria cannot be doing by humans. My claim is that the criteria created by these mathematical structures that I have observed prove this claim scientifically. Answering the question I asked above is possible with this mathematical structure, and it can be proved by this mathematical structure that a text brought is not like the Quran

After the Prophet, if people have made changes in the text of Qur’an, by adding, subtracting or changing one or more verses or even entire a section (Surah) by adding, subtracting or changing one, this mathematical structure would not have appeared in this way today, it would have been disrupted. But our observations show that the mathematical structure is intact and that the Qur’an is untouched, original and extraordinary that is the Word of Allah.
