Think not of those who are slain in the way of Allah, as dead. Nay, they are living. With their Lord, being sustained; Jubilant (are they) because of that which Allah has bestowed upon them of His bounty, rejoicing for the sake of those who have not joined them but are left behind: that there no fear shall come upon them, nor shall they grieve. They rejoice because of favour from Allah and He kindness, and that Allah does not wastes the reward of the believers. (Surah Ale Imran, 3: 169 -171)
