It was not [proper] for the people of Madīnah and those surrounding them of the bedouins that they remain behind after [the departure of] the Messenger of Allāh 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 Allāh, nor do they tread on any ground that enrages the disbelievers, nor do they inflict upon an enemy any infliction but that it is registered for them as a righteous deed. Indeed, Allāh does not allow to be lost the reward of the doers of good.
