Muhammad is but a messenger, messengers (the like of whom) have passed away before him. Will it be that, when he dieth or is slain, ye will turn back on your heels? He who turneth back on his heels doth no hurt to Allah, and Allah will reward the thankful. 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 how many a prophet has had to fight [in God's cause,] followed by many God-devoted men: and they did not become faint of heart for all that they had to suffer in God's cause, and neither did they weaken, nor did they abase themselves [before the enemy,] since God loves those who are patient in adversity; 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 And God gave them the reward of this world and the fairest reward of the world to come; and God loves the good-doers. 148
