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 It is not given to any soul to die except with the leave of Allah, and at an appointed time. And he who desires his reward in this world, We shall grant him the reward of this world; and he who desires the reward of the Other World, We shall grant him the reward of the Other World. And soon shall We reward the ones 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 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 whereupon God granted them the rewards of this world, as well as the goodliest rewards of the life to come: for God loves the doers of good. 148
