Muhammad is only a messenger. Messengers have passed away before him. If he should die, or be killed, will you turn back on your heels? Those who turn on their heels do not harm the Lord in the least. God 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 many a prophet hath fought with a number of godly men beside him. They fainted not for aught that befell them in the way of Allah, nor they weakened, nor they humbled themselves; and Allah loveth the steadfast. 146 Nothing else they said but, 'Lord, forgive us our sins, and that we exceeded in our affair, and make firm our feet, and help us against the people of 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
