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 for any soul to die except by the permission of Allah a postponed book; and he who desires the reward of this world, We shall give him of it, and he who desires the reward of the Everlasting Life, We shall give him of it. 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 Their only words were: 'Lord, forgive us our sins and that we exceeded in our affair, make us firm of foot and give us victory over the unbelievers' 147 God gave them their reward in this world and the best reward of the life to come. God loves the righteous ones. 148
