And whosoever blindeth himself to the admonition of the Compassionate, We assign unto him a satan, and he becometh his companion. 36 whereupon, behold, these [evil impulses] bar all such from the path [of truth,] making them think that they are guided aright! 37 But when he comes to Us, he will say (to his satan): “Would that there had been between me and you the distance as between the East and the West. How evil a companion you were!” 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 So will you make the deaf listen or show the path to the blind, and to those who are in open error? (The disbelievers whose hearts are sealed, are deaf and blind to the truth). 40 We shall punish them whether We take you away, 41 or make you see the end that We had promised them, for We have full power over them. 42 So hold fast to all that has been revealed to thee: for, behold, thou art on a straight way; 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
