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 And it is not [possible] for one to die except by permission of Allah at a decree determined. And whoever desires the reward of this world - We will give him thereof; and whoever desires the reward of the Hereafter - We will give him thereof. And we will reward the 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 The only words that they spoke were, "Lord, forgive our sins and our excess in our dealings, make us steadfast (in the fight for Your cause), and grant us victory over the unbelievers." 147 So Allah gave them the reward of this world and better reward of the hereafter and Allah loves those who do good (to others). 148
