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 It is not for any soul to die except by the permission of Allah a postponed book; and he who desires the reward of this world, We shall give him of it, and he who desires the reward of the Everlasting Life, We shall give him of it. And We will recompense the thankful. 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 Nothing else they said but, 'Lord, forgive us our sins, and that we exceeded in our affair, and make firm our feet, and help us against the people of the unbelievers.' 147 Wherefore Allah vouchsafed unto them the reward of the world, and the excellent reward of the Hereafter. And Allah loveth the well-doers. 148
