O believers, fear God, and be with the truthful ones. 119 It is not for the townsfolk of Al-Madinah and for those around them of the wandering Arabs to stay behind the messenger of Allah and prefer their lives to his life. That is because neither thirst nor toil nor hunger afflicteth them in the way of Allah, nor step they any step that angereth the disbelievers, nor gain they from the enemy a gain, but a good deed is recorded for them therefor. Lo! Allah loseth not the wages of the good. 120 Each sum they spend, be it small or large, and each valley they cross is written to their account, so that Allah may recompense them for their best deeds. 121 ۞ And it is not for the believers to go forth [to battle] all at once. For there should separate from every division of them a group [remaining] to obtain understanding in the religion and warn their people when they return to them that they might be cautious. 122
