Excellent resource on ring composition in the Qur'an

It has been a long time since I have posted here! I wanted to give a shout out here to Munir Eltal's blog https://heavenlyorder.substack.com. He is doing an excellent service by trying to collect everything together on symmetry, chiasmus, or ring composition in the Qur'an into one place. I have shared some examples here on my blog—but see his for many, many more.
