If you [disbelievers] seek the decision [i.e., victory] - the decision [i.e., defeat] has come to you. And if you desist [from hostilities], it is best for you; but if you return [to war], We will return, and never will you be availed by your [large] company at all, even if it should increase; and [that is] because Allāh is with the believers.
