Muhammad is only a messenger. Messengers have passed away before him. If he should die, or be killed, will you turn back on your heels? Those who turn on their heels do not harm the Lord in the least. God will reward the grateful. 144 No one can die before his appointed term except in accordance with the law of God. And to him who desires a reward in this world, We shall give it; and to him who desires a reward in the life to come, We shall do that. We shall certainly reward those who are grateful. 145 Many a seeker after God has fought in the way of God by the side of many an apostle, undaunted (by disaster), and did not disgrace themselves; -- verily God loves those who are steadfast. 146 All they said was, "Our Lord, forgive us our sins and our excesses. Make our feet firm, and help 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
