O believers, do not stray from the path of God, and be with those who are truthful. 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 Nor could they spend anything (for the cause) - small or great- nor cut across a valley, but the deed is inscribed to their credit: that Allah may requite their deed with the best (possible reward). 121 ۞ It is not right that all the believers should go out [in time of war] all together. Why, then, does not a party from every group come to [the Prophet] in order to acquire a deeper knowledge of religion and to warn their people, so that they can guard themselves against evil? 122
