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 It is not possible for any person to die except by Allah's command at a term recorded. And whosoever desireth the reward of the world, We vouchsafe unto him thereof; and whosoever desireth the reward of the Hereafter, We vouchsafe unto him thereof. And anon will we recompense the grateful. 145 And how many a prophet has fought with whom were many worshippers of the Lord; so they did not become weak-hearted on account of what befell them in Allah's way, nor did they weaken, nor did they abase themselves; and Allah 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 So God rewarded them in this world, and a better reward awaits them in the next; for God loves those who do good. 148
