فَليُقاتِل في سَبيلِ اللَّهِ الَّذينَ يَشرونَ الحَياةَ الدُّنيا بِالآخِرَةِ ۚ وَمَن يُقاتِل في سَبيلِ اللَّهِ فَيُقتَل أَو يَغلِب فَسَوفَ نُؤتيهِ أَجرًا عَظيمًا

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