Quran 9:64 — Ultimatum (Bara'ah)

The hypocrites worry that a sura may be revealed exposing what is inside their hearts. Say, "Go ahead and mock. GOD will expose exactly what you are afraid of."

[9:63] Did they not know that anyone who opposes GOD and His messenger has incurred the fire of Hell forever? This is the worst humiliation.

[9:65] If you ask them, they would say, "We were only mocking and kidding." Say, "Do you realize that you are mocking GOD, and His revelations, and His messenger?"
