Muhammad is only a messenger. Messengers have passed away before him. If he should die, or be killed, will you turn back on your heels? Those who turn on their heels do not harm the Lord in the least. God will reward the grateful. 144 And it is not [possible] for one to die except by permission of Allah at a decree determined. And whoever desires the reward of this world - We will give him thereof; and whoever desires the reward of the Hereafter - We will give him thereof. And we will reward the grateful. 145 Many godly people fought to help the Prophets in the cause of God. They did not lose courage, show weakness, or give in when facing hardships in their fight for the cause of God. God loves those who have patience. 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 Wherefore Allah vouchsafed unto them the reward of the world, and the excellent reward of the Hereafter. And Allah loveth the well-doers. 148
