Muhammad 47:4 فاذا لقيتم الذين كفروا فضرب الرقاب حتى اذا اثخنتموهم فشدوا الوثاق فاما منا بعد واما فداء حتى تضع الحرب اوزارها ذالك ولو يشاء الله لانتصر منهم ولاكن ليبلو بعضكم ببعض والذين قتلوا في سبيل الله فلن يضل اعمالهم ٤

So when you meet those who disbelieve [in battle], strike [their] necks until, when you have inflicted slaughter upon them, then secure [their] bonds,¹ and either [confer] favor² afterwards or ransom [them] until the war lays down its burdens.³ 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.
