To whosoever blinds himself from the Remembrance of the Merciful, We shall assign him a satan so he is his companion, 36 And lo! they surely turn them from the way of Allah, and yet they deem that they are rightly guided; 37 When he returns to us, he will say (to satan), "Would that there had been as long a distance between me and you as that between the East and West. What a terrible companion you have been". 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 (Muhammad), can you make the deaf hear or guide the blind or the one who is clearly in error? 40 But if We should take you away, still We shall inflict retribution on them; 41 Or whether [or not] We show you that which We have promised them, indeed, We are Perfect in Ability. 42 So hold thou fast to the Revelation sent down to thee; verily thou art on a Straight Way. 43 And verily, this (the Quran) is indeed a Reminder for you (O Muhammad SAW) and your people (Quraish people, or your followers), and you will be questioned (about it). 44 And ask those of Our messengers whom We sent before thee: Did We ever appoint gods to be worshipped beside the Beneficent? 45
