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 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 Many godly people fought to help the Prophets in the cause of God. They did not lose courage, show weakness, or give in when facing hardships in their fight for the cause of God. God loves those who have patience. 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 Wherefore Allah vouchsafed unto them the reward of the world, and the excellent reward of the Hereafter. And Allah loveth the well-doers. 148
