Quran 36:68 — Y.S. (Ya Sin)

Whomever we permit to live for a long time, we revert him to weakness. Do they not understand?

[36:67] If we will, we can freeze them in place; thus, they can neither move forward, nor go back.

[36:69] What we taught him (the messenger) was not poetry, nor is he (a poet). This is but a formidable proof,* and a profound Quran.
