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 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 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 So Allah gave them the reward of this world and the best of rewards in the Hereafter; and Allah loves the righteous. 148
