Quran and numbers

You can forget the frequencies of the words as they need program to find them, not this method--beside there are few that match.

If you notice Chapeter 36 and chapter 50 don't have names. Ya-seen are the 2 letters located at verse one, and the name Qof is derived from the letter Qof at verse one also. These two are nameless chapters. But there are two other chapters which also don't have names, they are chapter 20 called To-Ha and chapter 38 called Sod.
So the nameless chapters are 20,36,38 and 50. When we add them the result is divisible by 9.
20+36+38+50=144.

Also the verse numbers for that chapters when add them together the result also divisible by 9.
135+83+88+45=351.

I wrote this off the memory so please check it maybe I made a mistake.

These are the names other than the Prophets that are mentioned in the Qur'an. The good are 7 of them, the bad are also 7--unless If you think I missed a name or two as we do make mistakes, than please let me know,  otherwise it is good, 7 and 7.
Also if say, you believe that Dhul Qornain was a messenger than that will be different story.

I hope my contributions will trigger your interest with the Qur'an.

Within 29 chapters that begin with mysterious letters - there are three that begin with a single letter. They are chapter 38, 50 and 68.
I have counted the letter Nun in chapter 68 manually with my hand about 4 times and chapter 38 twice. Chapter 50 I use the program.

Chapter 38 has 29 Sod
Chapter 50 has 57 Qof
Chapter 68 has 131 Nun

Total  = 217--217/7 = 31

If we put the chapters and their verses together total 341--341/11=31.

There are 4 numbers that I used for this, they are no: 7, 9, 11 and 19.
