Believers, have fear of God and always be friends with the truthful 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 they expend not an expending, small or great, or transverse a vale, but it is written down unto them, so that Allah may recompense them with the best for that which they have been working. 121 ۞ It is not possible for all believers to go out (to fight). So a part of each section (of the population) should go (to fight) in order that the others may acquire understanding of law and divinity, and warn their companions on return so that they may take heed for themselves. 122
