O you who believe! be careful of (your duty to) Allah and be with the true ones. 119 The inhabitants of the city of Medina and the desert Arabs dwelling around it were not supposed to disobey the Messenger of God or to give priority to their own lives above that of the Prophet. For if they had given priority to the life of the Messenger of God, they would not have experienced the hardships of thirst, fatigue, or hunger in their struggle for the cause of God, nor would their travelling have enraged the disbelievers and they would not have received any injury from enemies that God would not record for them as a virtuous deed. God does not ignore the reward of those who do good. 120 and whenever they spend anything [for the sake of God], be it little or much, and whenever they traverse the land [in God's cause] -- it is recorded to their credit, and God will grant them the best reward for all that they have been doing. 121 ۞ Nor should the Believers all go forth together: if a contingent from every expedition remained behind, they could devote themselves to studies in religion, and admonish the people when they return to them,- that thus they (may learn) to guard themselves (against evil). 122
