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, save by the leave of God, at an appointed time. Whoso desires the reward of this world, We will give him of this; and whoso desires the reward of the other world, We will give him of that; and We will recompense 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 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 And God gave them the reward of this world and the fairest reward of the world to come; and God loves the good-doers. 148
