O you who believe! be careful of (your duty to) Allah and be with the true ones. 119 It was not [proper] for the people of Madinah and those surrounding them of the bedouins that they remain behind after [the departure of] the Messenger of Allah or that they prefer themselves over his self. That is because they are not afflicted by thirst or fatigue or hunger in the cause of Allah, nor do they tread on any ground that enrages the disbelievers, nor do they inflict upon an enemy any infliction but that is registered for them as a righteous deed. Indeed, Allah does not allow to be lost the reward of the doers of good. 120 And whatever they spend, small or great, or any valley they cross – it is all recorded for them, so that Allah may reward them for their best deeds. 121 ۞ And it is not possible for the Muslims that all of them go out; so it should be that a party from each group goes forth in order to gain knowledge in religion, and upon returning they warn their people in the hope that they may avoid. 122
