Surah An-Nisa, ayah 74

4:74

۞ فَلۡيُقَٰتِلۡ فِي سَبِيلِ ٱللَّهِ ٱلَّذِينَ يَشۡرُونَ ٱلۡحَيَوٰةَ ٱلدُّنۡيَا بِٱلۡأٓخِرَةِۚ وَمَن يُقَٰتِلۡ فِي سَبِيلِ ٱللَّهِ فَيُقۡتَلۡ أَوۡ يَغۡلِبۡ فَسَوۡفَ نُؤۡتِيهِ أَجۡرًا عَظِيمٗا ٧٤

Falyuqātil fī sabīlillāhil-ladhīna yashrūnal-hayawātad-dunyā bil-ākhirati waman yuqātil fī sabīlillāhi fayuqtal aw yaghlib fasawfa nu'tīhi ajran 'azīmā

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.
