Whoso blinds himself to the Remembrance of the All-merciful, to him We assign a Satan for comrade; 36 And indeed, the devils avert them from the way [of guidance] while they think that they are [rightly] guided 37 Until, when he comes to Us [at Judgement], he says [to his companion], "Oh, I wish there was between me and you the distance between the east and west - how wretched a companion." 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 Canst thou then make the deaf to hear, or give direction to the blind or to such as (wander) in manifest error? 40 Even if We take you away, We shall take vengeance upon them, 41 Or We shall show thee that (accomplished) which We have promised them: for verily We shall prevail over them. 42 So hold thou fast unto that which has been revealed unto thee; surely thou art upon a straight path. 43 And it is undoubtedly an honour for you and your people; and you will soon 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
