And whoever is blinded from remembrance of the Most Merciful - We appoint for him a devil, and he is to him a companion. 36 And lo! they surely turn them from the way of Allah, and yet they deem that they are rightly guided; 37 At length, when (such a one) comes to Us, he says (to his evil companion): "Would that between me and thee were the distance of East and West!" Ah! evil is the companion (indeed)! 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 Can you [Prophet] make the deaf hear? Or guide either the blind or those who are in manifest error? 40 We shall punish them whether We take you away, 41 Or show you what We have promised them – We therefore have complete control over them. 42 So adhere to that which is revealed to you. Indeed, you are on a straight path. 43 And lo! it is in truth a Reminder for thee and for thy folk; and 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
