﴿ ۞ فَلْيُقَٰتِلْ فِى سَبِيلِ ٱللَّهِ ٱلَّذِينَ يَشْرُونَ ٱلْحَيَوٰةَ ٱلدُّنْيَا بِٱلْءَاخِرَةِ ۚ وَمَن يُقَٰتِلْ فِى سَبِيلِ ٱللَّهِ فَيُقْتَلْ أَوْ يَغْلِبْ فَسَوْفَ نُؤْتِيهِ أَجْرًا عَظِيمًۭا ﴾

“Hence, let them fight in God's cause - all who are willing to barter the life of this world for the life to come: for unto him who fights in God's cause, whether he be slain or be victorious, We shall in time grant a mighty reward.”

See note to 2:191.
