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 they bar them from the Way, though they themselves think that they are guided. 37 Till, when (such a one) comes to Us, he says [to his Qarin (Satan / devil companion)] "Would that between me and you were the distance of the two easts (or the east and west)" a worst (type of) 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 CANST THOU, perchance, [O Muhammad,] make the deaf hear, or show the right way to the blind or to such as are obviously lost in error? 40 And if We take thee away, We surely shall take vengeance on them, 41 Or show you some of what We have promised them. They are certainly well within Our power. 42 So hold thou fast unto that which has been revealed unto thee; surely thou art upon a straight path. 43 It is indeed a Reminder to you and to your nation, and without doubt you shall 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
