And whoever is blinded from remembrance of the Most Merciful - We appoint for him a devil, and he is to him a 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 When ye have done wrong, it will avail you nothing, that Day, that ye shall be partners in Punishment! 39 Can you, (O Prophet), then make the deaf hear, or direct to the Right Way the blind or one lost in manifest error? 40 We shall punish them whether We take you away, 41 and whether We show thee [or do not show thee in this world] the fulfillment of what We have promised them - verily, We have full power over them! 42 Therefore hold fast to that which has been revealed to you; surely you are on the right path. 43 The (Qur'an) is indeed the message, for thee and for thy people; and soon shall ye (all) be brought to account. 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
