Quran 9:89 — Ultimatum (Bara'ah)

GOD has prepared for them gardens with flowing streams, wherein they abide forever. This is the greatest triumph.

[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.

[9:90] The Arabs made up excuses, and came to you seeking permission to stay behind. This is indicative of their rejection of GOD and His messenger—they stay behind. Indeed, those who disbelieve among them have incurred a painful retribution.
