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 person can ever die except by Allah's Leave and at an appointed term. And whoever desires a reward in (this) world, We shall give him of it; and whoever desires a reward in the Hereafter, We shall give him thereof. And We shall reward the grateful 145 How many a prophet has fought with many devout men alongside him! They did not lose heart, despite all that they had to suffer in God's path. They neither weakened nor yielded. 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 excellent reward of the Hereafter. And Allah loves Al-Muhsinun (the good-doers - see the footnote of V. 3:134). 148
