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 And how many a prophet has fought with whom were many worshippers of the Lord; so they did not become weak-hearted on account of what befell them in Allah's way, nor did they weaken, nor did they abase themselves; and Allah loves the patient. 146 All that they said was: "Our Lord! Forgive us our sins and anything We may have done that transgressed our duty: Establish our feet firmly, and help us against those that resist Faith." 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
