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 except with the leave of Allah, and at an appointed time. And he who desires his reward in this world, We shall grant him the reward of this world; and he who desires the reward of the Other World, We shall grant him the reward of the Other World. And soon shall We reward the ones who are grateful. 145 And with how many a prophet have there been a number of devoted men who fought (beside him). They quailed not for aught that befell them in the way of Allah, nor did they weaken, nor were they brought low. Allah loveth the steadfast. 146 Nor did they say aught but: "O our Lord, forgive us our sins and excesses in our acts, and steady our steps, and help us against unbelieving people." 147 And Allah gave them a reward in this world, and the excellent reward of the Hereafter. For Allah Loveth those who do good. 148
