Muhammad is not except a Messenger; Messengers have passed away before him. If he dies or is killed, will you turn about on your heels? And he who turns on his heels will not harm Allah a thing. Allah will recompense the thankful. 144 And no person can ever die except by Allah's Leave and at an appointed term. And whoever desires a reward in (this) world, We shall give him of it; and whoever desires a reward in the Hereafter, We shall give him thereof. And We shall reward the grateful 145 And how many a prophet has had to fight [in God's cause,] followed by many God-devoted men: and they did not become faint of heart for all that they had to suffer in God's cause, and neither did they weaken, nor did they abase themselves [before the enemy,] since God loves those who are patient in adversity; 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 God rewarded them in this world, and a better reward awaits them in the next; for God loves those who do good. 148
