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 except with the leave of Allah, and at an appointed time. And he who desires his reward in this world, We shall grant him the reward of this world; and he who desires the reward of the Other World, We shall grant him the reward of the Other World. And soon shall We reward the ones who are grateful. 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 their words were not but that they said, "Our Lord, forgive us our sins and the excess [committed] in our affairs and plant firmly our feet and give us victory over the disbelieving people." 147 and so God gave them both the rewards of this life and the excellent recompense of the life to come: God loves those who do good. 148
