Quran 9:83 — Ultimatum (Bara'ah)

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."

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

[9:84] You shall not observe the funeral prayer for any of them when he dies, nor shall you stand at his grave. They have disbelieved in GOD and His messenger, and died in a state of wickedness.
