And [He also forgave] the three who were left alone [i.e., boycotted, regretting their error] to the point that the earth closed in on them in spite of its vastness¹ and their souls confined [i.e., anguished] them and they were certain that there is no refuge from Allāh except in Him. Then He turned to them so they could repent. Indeed, Allāh is the Accepting of Repentance,² the Merciful.

O you who have believed, fear Allāh and be with those who are true.

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.¹ 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.

Nor do they spend an expenditure, small or large, or cross a valley but that it is registered for them that Allāh may reward them for the best of what they were doing.

And it is not for the believers to go forth [to battle] all at once. For there should separate from every division of them a group [remaining] to obtain understanding in the religion and warn [i.e., advise] their people when they return to them that they might be cautious.
