"Therefore, when ye meet the Unbelievers [in fight], smite at their necks; At length, when ye have thoroughly subdued them, bind a bond firmly [on them]: thereafter [is the time for] either generosity or ransom: Until the war lays down its burdens. Thus [are ye commanded]: but if it had been Allah's Will, He could certainly have exacted retribution from them [Himself]; but [He lets you fight] in order to test you, some with others. But those who are slain in the Way of Allah,- He will never let their deeds be lost."— Yusuf Ali translation
