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 before his appointed term except in accordance with the law of God. And to him who desires a reward in this world, We shall give it; and to him who desires a reward in the life to come, We shall do that. We shall certainly reward those who are grateful. 145 There has been many a Prophet with whom many of the Lord have fought and they did not faint when they were smitten in the way of Allah, neither did they weaken, nor did they humble themselves, and Allah loves the patient. 146 And their speech was naught but that they said: our Lord! forgive us our sins and our extravagance in our affairs, and make our foothold firm, and make us triumph over the disbelieving people. 147 So Allah gave them the reward of the world and the good reward of the Hereafter. Allah loveth those whose deeds are good. 148
