Muhammad (SAW) is no more than a Messenger, and indeed (many) Messengers have passed away before him. If he dies or is killed, will you then turn back on your heels (as disbelievers)? And he who turns back on his heels, not the least harm will he do to Allah, and Allah will give reward to those who are grateful. 144 Nor can a soul die except by Allah's leave, the term being fixed as by writing. If any do desire a reward in this life, We shall give it to him; and if any do desire a reward in the Hereafter, We shall give it to him. And swiftly shall We reward those that (serve us with) gratitude. 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 All that they said was: "Our Lord! Forgive us our sins and anything We may have done that transgressed our duty: Establish our feet firmly, and help us against those that resist Faith." 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
