O you who have believed, fear Allah and be with those who are true. 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 Nor do they spend an expenditure, small or large, or cross a valley but that it is registered for them that Allah may reward them for the best of what they were doing. 121 ۞ And it is not (proper) for the believers to go out to fight (Jihad) all together. Of every troop of them, a party only should go forth, that they (who are left behind) may get instructions in (Islamic) religion, and that they may warn their people when they return to them, so that they may beware (of evil). 122
