Whoso blinds himself to the Remembrance of the All-merciful, to him We assign a Satan for comrade; 36 whereupon, behold, these [evil impulses] bar all such from the path [of truth,] making them think that they are guided aright! 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 Then will you make the deaf hear, [O Muhammad], or guide the blind or he who is in clear error? 40 But if We should take you away, still We shall inflict retribution 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 that which is inspired in thee. Lo! thou art on a right path. 43 And lo! it is in truth a Reminder for thee and for thy folk; and ye will be questioned. 44 And ask those of Our messengers whom We sent before thee: Did We ever appoint gods to be worshipped beside the Beneficent? 45
