۞ فَلْيُقَٰتِلْ فِى سَبِيلِ ٱللَّهِ ٱلَّذِينَ يَشْرُونَ ٱلْحَيَوٰةَ ٱلدُّنْيَا بِٱلْءَاخِرَةِ ۚ وَمَن يُقَٰتِلْ فِى سَبِيلِ ٱللَّهِ فَيُقْتَلْ أَوْ يَغْلِبْ فَسَوْفَ نُؤْتِيهِ أَجْرًا عَظِيمًۭا
Let those fight in the way of Allah who sell the life of this world for the other. Whoso fighteth in the way of Allah, be he slain or be he victorious, on him We shall bestow a vast reward.
