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 a soul will not die but with the permission of Allah the term is fixed; and whoever desires the reward of this world, I shall give him of it, and whoever desires the reward of the hereafter I shall give him of it, and I will reward the grateful. 145 There has been many a Prophet with whom many of the Lord have fought and they did not faint when they were smitten in the way of Allah, neither did they weaken, nor did they humble themselves, and Allah loves the patient. 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 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
