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 And it is not [possible] for one to die except by permission of Allah at a decree determined. And whoever desires the reward of this world - We will give him thereof; and whoever desires the reward of the Hereafter - We will give him thereof. And we will reward the grateful. 145 Many a seeker after God has fought in the way of God by the side of many an apostle, undaunted (by disaster), and did not disgrace themselves; -- verily God loves those who are steadfast. 146 Their cry was only that they said: Our Lord! forgive us for our sins and wasted efforts, make our foothold sure, and give us victory over the disbelieving folk. 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
