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 human being can die save by God's leave, at a term pre-ordained. And if one desires the rewards of this world, We shall grant him thereof; and if one desires the rewards of the life to come, We shall grant him thereof; and We shall requite those who are grateful [to Us]. 145 And many Prophets have fought in Allah’s cause – and many devoted men were with them; so neither did they lose heart due to the calamities that befell them in Allah's cause, nor did they weaken and nor were they subdued; and the steadfast are the beloved of Allah. 146 Their only words were: 'Lord, forgive us our sins and that we exceeded in our affair, make us firm of foot and give us victory over the unbelievers' 147 And God gave them the reward of this world and the fairest reward of the world to come; and God loves the good-doers. 148
