Quran 9:87 — Ultimatum (Bara'ah)

They chose to be with the sedentary. Consequently, their hearts were sealed, and thus, they cannot comprehend.

[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!"

[9:88] As for the messenger and those who believed with him, they eagerly strive with their money and their lives. These have deserved all the good things; they are the winners.
