Muhammad is not but a messenger. [Other] messengers have passed on before him. So if he was to die or be killed, would you turn back on your heels [to unbelief]? And he who turns back on his heels will never harm Allah at all; but Allah will reward the grateful. 144 And a soul will not die but with the permission of Allah the term is fixed; and whoever desires the reward of this world, I shall give him of it, and whoever desires the reward of the hereafter I shall give him of it, and I will reward the grateful. 145 Many a Prophet there has been, with whom thousands manifold have fought, and they fainted not for what smote them in God's way, neither weakened, nor did they humble themselves; and God loves the patient. 146 The only words that they spoke were, "Lord, forgive our sins and our excess in our dealings, make us steadfast (in the fight for Your cause), and grant us victory over the unbelievers." 147 And God gave them the reward of this world and the fairest reward of the world to come; and God loves the good-doers. 148
