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 for any soul to die except by the permission of Allah a postponed book; and he who desires the reward of this world, We shall give him of it, and he who desires the reward of the Everlasting Life, We shall give him of it. And We will recompense the thankful. 145 And many Prophets have fought in Allah’s cause – and many devoted men were with them; so neither did they lose heart due to the calamities that befell them in Allah's cause, nor did they weaken and nor were they subdued; and the steadfast are the beloved of Allah. 146 Their cry was only that they said: Our Lord! forgive us for our sins and wasted efforts, make our foothold sure, and give us victory over the disbelieving folk. 147 So Allah gave them the reward of this world and the good reward of the Hereafter. And Allah loves the doers of good. 148
