Quran 9:85 — Ultimatum (Bara'ah)

Do not be impressed by their money or their children; GOD causes these to be sources of misery for them in this world, and their souls depart as disbelievers.

[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.

[9:86] When a sura is revealed, stating: "Believe in GOD, and strive with His messenger," even the strong among them say, "Let us stay behind!"
