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 It is not given to any soul to die, save by the leave of God, at an appointed time. Whoso desires the reward of this world, We will give him of this; and whoso desires the reward of the other world, We will give him of that; and We will recompense the thankful. 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 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 whereupon God granted them the rewards of this world, as well as the goodliest rewards of the life to come: for God loves the doers of good. 148
