Muhammad is but a messenger, messengers (the like of whom) have passed away before him. Will it be that, when he dieth or is slain, ye will turn back on your heels? He who turneth back on his heels doth no hurt to Allah, and Allah will reward the thankful. 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 Many were the Prophets on whose side a large number of God-devoted men fought: they neither lost heart for all they had to suffer in the way of Allah nor did they weaken nor did they abase themselves. Allah loves such steadfast ones. 146 The only words that they spoke were, "Lord, forgive our sins and our excess in our dealings, make us steadfast (in the fight for Your cause), and grant us victory over 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
