Muhammad is not but a messenger. [Other] messengers have passed on before him. So if he was to die or be killed, would you turn back on your heels [to unbelief]? And he who turns back on his heels will never harm Allah at all; but Allah 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 And many a prophet hath fought with a number of godly men beside him. They fainted not for aught that befell them in the way of Allah, nor they weakened, nor they humbled themselves; and Allah loveth the steadfast. 146 And all they said was this: 'Our Lord! Forgive us our sins, and our excesses, and set our feet firm, and succour us against those who deny the Truth.' 147 And Allah gave them a reward in this world, and the excellent reward of the Hereafter. For Allah Loveth those who do good. 148
