O ye who believe! Be careful of your duty to Allah, and be with the truthful. 119 It is not for the people of the City and for the Bedouins who dwell around them to stay behind God's Messenger, and to prefer their lives to his; that is because they are smitten neither by thirst, nor fatigue, nor emptiness in the way of God, neither tread they any tread enraging the unbelievers, nor gain any gain from any enemy, but a righteous deed is thereby written to their account; God leaves not to waste the wage of the good-doers. 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 ۞ 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
