Quran 9:119 — Ultimatum (Bara'ah)

O you who believe, you shall reverence GOD, and be among the truthful.

[9:118] Also (redeemed were) the three who stayed behind. The spacious earth became so straitened for them, that they almost gave up all hope for themselves. Finally, they realized that there was no escape from GOD, except to Him. He then redeemed them that they may repent. GOD is the Redeemer, Most Merciful.

[9:120] Neither the dwellers of the city, nor the Arabs around them, shall seek to stay behind the messenger of GOD (when he mobilizes for war). Nor shall they give priority to their own affairs over supporting him. This is because they do not suffer any thirst, or any effort, or hunger in the cause of GOD, or make a single step that enrages the disbelievers, or inflict any hardship upon the enemy, without having it written down for them as a credit. GOD never fails to recompense those who work righteousness.
