And whosoever blindeth himself to the admonition of the Compassionate, We assign unto him a satan, and he becometh his companion. 36 Satan will prevent them from the right path while they think that they have the right guidance. 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 What! can you then make the deaf to hear or guide the blind and him who is in clear error? 40 So if We take you away, We shall then indeed take revenge from them. 41 or show them to you suffering the torment with which We had threatened them. We are certainly dominant over them all. 42 So hold fast to what has been revealed to you. Surely you are on the Straight Way. 43 The (Qur'an) is indeed the message, for thee and for thy people; and soon shall ye (all) be brought to account. 44 Ask Our Messengers whom We sent before you if We have ever made gods, other than the Merciful, to be worshipped. 45
