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 were the Prophets on whose side a large number of God-devoted men fought: they neither lost heart for all they had to suffer in the way of Allah nor did they weaken nor did they abase themselves. Allah loves such steadfast ones. 146 And they said nothing but: "Our Lord! Forgive us our sins and our transgressions (in keeping our duties to You), establish our feet firmly, and give us victory over the disbelieving folk." 147 whereupon God granted them the rewards of this world, as well as the goodliest rewards of the life to come: for God loves the doers of good. 148
