Falyuqaatil fee sabeelil laahil lazeena yashroonal hayaatad dunyaa bil Aakhirah; wa many-uqaatil fee sabeelil laahi fa yuqtal aw yaghlib fasawfa nu'teehi ajran 'azeemaa
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.
1 Mufti Taqi Usmani
So, those who sell the worldly life for the Hereafter should fight in the way of Allah. Whoever fights in the way of Allah, then gets killed or prevails, We shall give a great reward to him.
