فَإِذَا لَقِيتُمُ ٱلَّذِينَ كَفَرُوا۟ فَضَرْبَ ٱلرِّقَابِ حَتَّىٰٓ إِذَآ أَثْخَنتُمُوهُمْ فَشُدُّوا۟ ٱلْوَثَاقَ فَإِمَّا مَنًّۢا بَعْدُ وَإِمَّا فِدَآءً حَتَّىٰ تَضَعَ ٱلْحَرْبُ أَوْزَارَهَا ۚ ذَٰلِكَ وَلَوْ يَشَآءُ ٱللَّهُ لَٱنتَصَرَ مِنْهُمْ وَلَـٰكِن لِّيَبْلُوَا۟ بَعْضَكُم بِبَعْضٍ ۗ وَٱلَّذِينَ قُتِلُوا۟ فِى سَبِيلِ ٱللَّهِ فَلَن يُضِلَّ أَعْمَـٰلَهُمْ

When you meet the disbelievers in battle, strike them in the neck, and once they are defeated, bind any captives firmly––later you can release them by grace or by ransom––until the toils of war have ended. That [is the way]. God could have defeated them Himself if He had willed, but His purpose is to test some of you by means of others. He will not let the deeds of those who are killed for His cause come to nothing;
So when you meet in battle those who deny the truth, strike at the necks until, when you have overwhelmed them, bind them firmly. Then afterward, either release them as a favor or for ransom, until war lays down its burdens. So it is. Had God willed, he could have taken retribution from them himself, but he tests some of you by means of others. As for those who are killed in the path of God, he will never let their deeds go to waste.
