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 No one can die without the permission of God. This is a written decree of the appointed term for life. We shall give worldly gains to whoever wants them. Those who want rewards in the life hereafter will also receive them. We reward those who give thanks. 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 Nothing else they said but, 'Lord, forgive us our sins, and that we exceeded in our affair, and make firm our feet, and help us against the people of the unbelievers.' 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
