And whosoever blindeth himself to the admonition of the Compassionate, We assign unto him a satan, and he becometh his companion. 36 Surely the (devils) obstruct them from the path, though they think they are rightly guided, -- 37 But in the end, when he [who has thus sinned] appears before us [on Judgment Day,] he will say [to his other self,] "Would that between me and thee there had been the distance of east and west!" for, evil indeed [has proved] that other self! 38 It will be said [to such a person], "You have done wrong. Having partners in punishment will be of no avail to you today." 39 CANST THOU, perchance, [O Muhammad,] make the deaf hear, or show the right way to the blind or to such as are obviously lost in error? 40 Even if We take you away, We shall take vengeance upon them, 41 Or whether [or not] We show you that which We have promised them, indeed, We are Perfect in Ability. 42 So adhere to that which is revealed to you. Indeed, you are on a straight path. 43 And indeed, it is a remembrance for you and your people, and you [all] are going to be questioned. 44 Ask those of Our Messengers We sent before thee: Have We appointed, apart from the All-merciful, gods to be served? 45
