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 given to any soul to die, save by the leave of God, at an appointed time. Whoso desires the reward of this world, We will give him of this; and whoso desires the reward of the other world, We will give him of that; and We will recompense the thankful. 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 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 the world and the good reward of the Hereafter. Allah loveth those whose deeds are good. 148
