Whoso blinds himself to the Remembrance of the All-merciful, to him We assign a Satan for comrade; 36 and these satans hinder them from the Right Path, while he still reckons himself to be 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 What! can you then make the deaf to hear or guide the blind and him who is in clear error? 40 But if We should take you away, still We shall inflict retribution 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 hold fast to all that has been revealed to thee: for, behold, thou art on a straight way; 43 and, verily, this [revelation] shall indeed become [a source of] eminence for thee and thy people: but in time you all will be called to account [for what you have done with it]. 44 Ask those of Our messengers whom We sent before you, "Did We ever appoint gods to be worshipped besides the Beneficent One?" 45
