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 And how many a prophet has fought with whom were many worshippers of the Lord; so they did not become weak-hearted on account of what befell them in Allah's way, nor did they weaken, nor did they abase themselves; and Allah loves the patient. 146 and all that they said was this: "O our Sustainer! Forgive us our sins and the lack of moderation in our doings! And make firm our steps, and succour us against people who deny the truth!" 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
