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 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 many a Prophet (i.e. many from amongst the Prophets) fought (in Allah's Cause) and along with him (fought) large bands of religious learned men. But they never lost heart for that which did befall them in Allah's Way, nor did they weaken nor degrade themselves. And Allah loves As-Sabirin (the patient ones, etc.). 146 And all they said was this: 'Our Lord! Forgive us our sins, and our excesses, and set our feet firm, and succour us against those who deny the Truth.' 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
