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 And a soul will not die but with the permission of Allah the term is fixed; and whoever desires the reward of this world, I shall give him of it, and whoever desires the reward of the hereafter I shall give him of it, and I will reward the grateful. 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 Nothing else they said but, 'Lord, forgive us our sins, and that we exceeded in our affair, and make firm our feet, and help us against the people of the unbelievers.' 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
