Muhammad is only a Messenger. There lived other Messengers before him. Should (Muhammad) die or be slain, would you then turn back to your pre-Islamic behavior? Whoever does so can cause no harm to God. God will reward those who give thanks. 144 It is not given to any soul to die except with the leave of Allah, and at an appointed time. And he who desires his reward in this world, We shall grant him the reward of this world; and he who desires the reward of the Other World, We shall grant him the reward of the Other World. And soon shall We reward the ones who are grateful. 145 And with how many a prophet have there been a number of devoted men who fought (beside him). They quailed not for aught that befell them in the way of Allah, nor did they weaken, nor were they brought low. Allah loveth the steadfast. 146 Their cry was only that they said: Our Lord! forgive us for our sins and wasted efforts, make our foothold sure, and give us victory over the disbelieving folk. 147 whereupon God granted them the rewards of this world, as well as the goodliest rewards of the life to come: for God loves the doers of good. 148
