O you who believe! be careful of (your duty to) Allah and be with the true ones. 119 It did not befit the people of Medinah and the people of the villages around them, to stay behind the Noble Messenger of Allah, nor to consider their own lives dearer than his life; that is because the thirst or the pain or the hunger that afflicts them in Allah's cause, and the step they tread on a place that angers the disbelievers, and whatever harm they cause the enemy – a good deed is recorded for them in lieu of all of these; indeed Allah does not waste the wages of the virtuous. 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 ۞ 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
