Surah An-Nisa 4:74

۞ فَلْيُقَـٰتِلْ فِى سَبِيلِ ٱللَّهِ ٱلَّذِينَ يَشْرُونَ ٱلْحَيَوٰةَ ٱلدُّنْيَا بِٱلْـَٔاخِرَةِ ۚ وَمَن يُقَـٰتِلْ فِى سَبِيلِ ٱللَّهِ فَيُقْتَلْ أَوْ يَغْلِبْ فَسَوْفَ نُؤْتِيهِ أَجْرًا عَظِيمًا

So let those fight in the cause of Allāh who sell the life of this world for the Hereafter. And he who fights in the cause of Allāh and is killed or achieves victory - We will bestow upon him a great reward.

Translation: Saheeh International
