Muhammad 47:4

When you encounter the disbelievers [in battle], strike [their] necks until you have thoroughly subdued them, then bind the captives firmly[2]. Later [you may free them] as a favor[3] or for ransom until the war comes to an end[4]. That [is Our command], if Allah had willed, He could have subjected them to punishment, but [He ordered you to fight] to test some of you by means of others. Those who are killed in the way of Allah, He will never render their deeds void.

[2] i.e., seize those remaining fighters as captives.
[3] i.e., release them without taking any ransom.
[4] lit., until the war lays down its burdens, its armor.

So when you meet those who disbelieve [in battle], strike [their] necks until, when you have inflicted slaughter upon them, then secure [their] bonds,[1494] and either [confer] favor[1495] afterwards or ransom [them] until the war lays down its burdens.[1496] That [is the command]. And if Allāh had willed, He could have taken vengeance upon them [Himself], but [He ordered armed struggle] to test some of you by means of others. And those who are killed in the cause of Allāh - never will He waste their deeds.

[1494] i.e., take those remaining as captives.
[1495] i.e., release them without ransom.
[1496] i.e., its armor, machinery, etc., meaning "until the war is over."

4. So, when you meet (in fight - Jihâd in Allâh’s Cause) those who disbelieve, smite (their) necks till when you have killed and wounded many of them, then bind a bond firmly (on them, i.e. take them as captives). Thereafter (is the time) either for generosity (i.e. free them without ransom), or ransom (according to what benefits Islâm), until the war lays down its burden. Thus [you are ordered by Allâh to continue in carrying out Jihâd against the disbelievers till they embrace Islâm and are saved from the punishment in the Hell-fire or at least come under your protection], but if it had been Allâh’s Will, He Himself could certainly have punished them (without you). But (He lets you fight) in order to test some of you with others. But those who are killed in the Way of Allâh, He will never let their deeds be lost.[2]

[2] (V.47:4) See the footnote of (V.2:190) and (V.9:20).

Now when ye meet in battle those who disbelieve, then it is smiting of the necks until, when ye have routed them, then making fast of bonds; and afterward either grace or ransom till the war lay down its burdens. That (is the ordinance). And if Allah willed He could have punished them (without you) but (thus it is ordained) that He may try some of you by means of others. And those who are slain in the way of Allah, He rendereth not their actions vain.
