Surah Al-Anfal Ayahs #20 Translated in English

And whoever turns his back to them on such a day, unless swerving [as a strategy] for war or joining [another] company, has certainly returned with anger [upon him] from Allāh, and his refuge is Hell - and wretched is the destination.

And you did not kill them, but it was Allāh who killed them. And you threw not, [O Muḥammad], when you threw, but it was Allāh who threw that He might test the believers with a good test. Indeed, Allāh is Hearing and Knowing.

That [is so], and [also] that Allāh will weaken the plot of the disbelievers.

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.

O you who have believed, obey Allāh and His Messenger and do not turn from him while you hear [his order].
