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 No soul can ever die except by Allah's leave and at a term appointed. Whoso desireth the reward of the world, We bestow on him thereof; and whoso desireth the reward of the Hereafter, We bestow on him thereof. We shall reward the thankful. 145 Many a seeker after God has fought in the way of God by the side of many an apostle, undaunted (by disaster), and did not disgrace themselves; -- verily God loves those who are steadfast. 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 So Allah gave them the reward of this world and the good reward of the Hereafter. And Allah loves the doers of good. 148
