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 It is not possible for any person to die except by Allah's command at a term recorded. And whosoever desireth the reward of the world, We vouchsafe unto him thereof; and whosoever desireth the reward of the Hereafter, We vouchsafe unto him thereof. And anon will we recompense the grateful. 145 There has been many a Prophet with whom many of the Lord have fought and they did not faint when they were smitten in the way of Allah, neither did they weaken, nor did they humble themselves, and Allah loves the patient. 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 so God gave them both the rewards of this life and the excellent recompense of the life to come: God loves those who do good. 148
