And he whose sight is dim to the remembrance of the Beneficent, We assign unto him a devil who becometh his comrade; 36 Satan will prevent them from the right path while they think that they have the right guidance. 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 They will be told on the Day of Judgment, "Regret will never be of any benefit to you. You have done injustice to your souls and you will share the torment". 39 What! can you then make the deaf to hear or guide the blind and him who is in clear error? 40 Even if We take thee away, We shall be sure to exact retribution from them, 41 Or show you some of what We have promised them. They are certainly well within Our power. 42 Therefore hold fast to that which has been revealed to you; surely you are on the right path. 43 and, verily, this [revelation] shall indeed become [a source of] eminence for thee and thy people: but in time you all will be called to account [for what you have done with it]. 44 And question thou our messengers whom We sent before thee; did We appoint any deities other than (Allah) Most Gracious, to be worshipped? 45
