O ye who believe! Fear Allah and be with those who are true (in word and deed). 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 Also, they would not have spent anything, great or small, for the cause of God or travel through a valley without God decreeing a reward for them far better than whatever they had done. 121 ۞ And it is not for the believers to march forth all together. So why should not a band from each party of them march forth so that they may gain understanding in religion and that when they come back unto them, haply they might warn their people when they come back unto them, haply they may beware! 122
