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 No one can die without the permission of God. This is a written decree of the appointed term for life. We shall give worldly gains to whoever wants them. Those who want rewards in the life hereafter will also receive them. We reward those who give thanks. 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 Nor did they say aught but: "O our Lord, forgive us our sins and excesses in our acts, and steady our steps, and help us against unbelieving people." 147 So Allah gave them the reward of this world and the best of rewards in the Hereafter; and Allah loves the righteous. 148
