O you who believe! be careful of (your duty to) Allah and be with the true 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 Also, they would not have spent anything, great or small, for the cause of God or travel through a valley without God decreeing a reward for them far better than whatever they had done. 121 ۞ And it is not for the believers to march forth all together. So why should not a band from each party of them march forth so that they may gain understanding in religion and that when they come back unto them, haply they might warn their people when they come back unto them, haply they may beware! 122
