To whosoever blinds himself from the Remembrance of the Merciful, We shall assign him a satan so he is his companion, 36 Surely the (devils) obstruct them from the path, though they think 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 And even if We take you (O Muhammad SAW) away, We shall indeed take vengeance on them. 41 Rather We will certainly show you that which We have promised them; for surely We are the possessors of full power over them. 42 So adhere to that which is revealed to you. Indeed, you are on a straight path. 43 And it is undoubtedly an honour for you and your people; and you will soon be questioned. 44 And ask (O Muhammad SAW) those of Our Messengers whom We sent before you: "Did We ever appoint aliha (gods) to be worshipped besides the Most Beneficent (Allah)?" 45
