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 And no soul can die except by Allah’s command – a time has been appointed for each; whoever desires the rewards of this world, We bestow upon him from it; and whoever desires the reward of the Hereafter, We bestow upon him from it; and We shall soon reward the thankful. 145 Many a Prophet there has been, with whom thousands manifold have fought, and they fainted not for what smote them in God's way, neither weakened, nor did they humble themselves; and God loves the patient. 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 So Allah gave them the reward of this world and the best of rewards in the Hereafter; and Allah loves the righteous. 148
