He who is negligent to remember the Merciful One, to him We assign a satan as his boon companion, 36 Surely the (devils) obstruct them from the path, though they think 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 And never will it benefit you that Day, when you have wronged, that you are [all] sharing in the punishment. 39 Can you make the deaf to hear, or show the blind, and those lost in clear error, the way? 40 We shall revenge them either after your death 41 or make you see the end that We had promised them, for We have full power over them. 42 So hold thou fast to the Revelation sent down to thee; verily 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
