Quran 9:82 — Ultimatum (Bara'ah)

Let them laugh a little, and cry a lot. This is the requital for the sins they have earned.

[9:81] 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.

[9:83] If GOD returns you to a situation where they ask your permission to mobilize with you, you shall say, "You will never again mobilize with me, nor will you ever fight with me against any enemy. For you have chosen to be with the sedentary in the first place. Therefore, you must stay with the sedentary."
