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 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 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 So Allah gave them the reward of the world and the good reward of the Hereafter. Allah loveth those whose deeds are good. 148
