Quran 9:81 — Ultimatum (Bara'ah)

The sedentary rejoiced in their staying behind the messenger of GOD, and hated to strive with their money and their lives in the cause of GOD. They said, "Let us not mobilize in this heat!" Say, "The fire of Hell is much hotter," if they could only comprehend.

[9:80] Whether you ask forgiveness for them, or do not ask forgiveness for them—even if you ask forgiveness for them seventy times—GOD will not forgive them. This is because they disbelieve in GOD and His messenger. GOD does not guide the wicked people.

[9:82] Let them laugh a little, and cry a lot. This is the requital for the sins they have earned.
