Then there are some who say, "We believe in Allah and the Last Day", whereas they do not believe at all. 8 Fain would they deceive Allah and those who believe, but they only deceive themselves, and realise (it) not! 9 In their hearts is disease, so Allah has increased their disease; and for them is a painful punishment because they [habitually] used to lie. 10 When it is said to them, 'Do not corruption in the land', they say, 'We are only ones that put things right.' 11 Now surely they themselves are the mischief makers, but they do not perceive. 12 And when it said unto them: believe even as mankind have believed, they say: shall we believe even as the fools have believed? Lo! verily it is they who are the fools; and yet they know not. 13 When they meet those who believe, they say, "We, too, are believers", but when they privily meet their evil geniuses, they say, "Indeed we are with you: we are only mocking at these people". 14 [But] Allah mocks them and prolongs them in their transgression [while] they wander blindly. 15 Those are the ones who have purchased error [in exchange] for guidance, so their transaction has brought no profit, nor were they guided. 16 They are like those who kindled a fire, and when it lighted up all around them, God took away their sight and left them in utter darkness, unable to see -- 17 deaf, dumb, blind -- so they shall not return; 18 Or, like (those who, under) a cloudburst from the sky with darkness, thunder and lightning, they thrust their fingers in their ears at the sound of every thunderclap for fear of death, and Allah encompasses the unbelievers. 19 The lightning almost snatcheth away their sight from them. As often as it flasheth forth for them they walk therein, and when it darkeneth against them they stand still. If Allah willed, He could destroy their hearing and their sight. Lo! Allah is able to do all things. 20
