symmetry in the Qur'an

39:23 Allah has revealed the best announcement, a book conformable in its various parts, repeating, whereat do shudder the skins of those who fear their Lord, then their skins and their hearts become pliant to the remembrance of Allah; this is Allah's guidance, He guides with it whom He pleases; and (as for) him whom Allah makes err, there is no guide for him.

very interesting stuff. a math-approach to the Qur'an,
but not that code-19 stuff.

many examples of symmetry in the arrangement of the
Qur'an.
