when you meet the faithless in battle strike their necks. when you have thoroughly decimated them bind the captives firmly. thereafter either oblige them or take ransom until the war lays down its burdens. that . had allah wished he could have taken vengeance on them but that he may test some of you by means of others. as for those who were slain in the way of allah he will not let their works go fruitless.
فإذا لقيتم الذين كفروا فضرب الرقاب حتى إذا أثخنتموهم فشدوا الوثاق فإما منا بعد وإما فداء حتى تضع الحرب أوزارها ذلك ولو يشاء الله لانتصر منهم ولكن ليبلو بعضكم ببعض والذين قتلوا في سبيل الله فلن يضل أعمالهم
