I chose only the suras that have a prime distance from Alhadeed. Surprisingly, above Alhadeed there are only 10 with prime distances. After it there is only one (Alqalam) and it is 11 away. I then chose any suras with primes (I have to play a little till I found the right ones).

The suras are 10, 14, 20, 26, 28, 38, 40, 44, 46, 50, 57, 68,74, 88, 98, 100, 104, 106, 110
The total of the sura numbers is 1121 which is the same as the total of ayas in the suras. 1121 = 19 * 59. Sura Alhadeed, 57, is in the center of the group..
