Quran 9:86 — Ultimatum (Bara'ah)

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

[9:85] 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.

[9:87] They chose to be with the sedentary. Consequently, their hearts were sealed, and thus, they cannot comprehend.
