And whoever is blinded from remembrance of the Most Merciful - We appoint for him a devil, and he is to him a companion. 36 and these satans hinder them from the Right Path, while he still reckons himself to be rightly-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 What, shalt thou make the deaf to hear, or shalt thou guide the blind and him who is in manifest error? 40 We shall punish them whether We take you away, 41 and whether We show thee [or do not show thee in this world] the fulfillment of what We have promised them - verily, We have full power over them! 42 Therefore hold fast to that which has been revealed to you; surely you are on the right path. 43 And indeed, it is a remembrance for you and your people, and you [all] are going to be questioned. 44 Yet [above all else,] ask any of Our apostles whom We sent forth before thy time whether We have ever allowed that deities other than the Most Gracious be worshipped! 45
