And whosoever turns away (blinds himself) from the remembrance of the Most Beneficent (Allah) (i.e. this Quran and worship of Allah), We appoint for him Shaitan (Satan - devil) to be a Qarin (an intimate companion) to him. 36 And lo! they surely turn them from the way of Allah, and yet they deem that they are rightly guided; 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 Canst thou (Muhammad) make the deaf to hear, or canst thou guide the blind or him who is in error manifest? 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 Follow devotedly that which is revealed to you. You are certainly on the right path. 43 The Quran is a reminder to you and to your people and you will soon be questioned about it. 44 Ask those of Our Messengers We sent before thee: Have We appointed, apart from the All-merciful, gods to be served? 45
