We shall attach to him who goes blind to the remembrance of Ar-Rahman a devil as companion, -- 36 and they bar them from the Way, though they themselves think that they are 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 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 (Muhammad), can you make the deaf hear or guide the blind or the one who is clearly in error? 40 And if We take thee away, We surely shall take vengeance on them, 41 or We show thee a part of that We promised them, surely We have power over them. 42 So hold thou fast to the Revelation sent down to thee; verily thou art on a Straight Way. 43 And verily it is an admonition unto thee and thy people; and presently ye will be questioned. 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
