بِسْمِ اللَّهِ الرَّحْمَٰنِ الرَّحِيمِ
In the name of Allah, Most Gracious, Most Merciful.
47:4
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
47:4
So, when you meet those who disbelieve (in battle), smite (their) necks until you have fully defeated them, then tighten their bonds. Thereafter (is the time) either for generosity or ransom, until the war lays down its burden. Thus, and had Allah so willed, He could have taken vengeance against them;--but (He lets you struggle) so as to test with one another. But those who are killed in the way of Allah, He will never let their deeds be lost. - Safi-ur-Rahman al-Mubarakpuri (English)
