And of mankind are some who say: We believe in Allah and the Last Day, when they believe not. 8 They (think to) deceive Allah and those who believe, while they only deceive themselves, and perceive (it) not! 9 In their hearts is a disease; and Allah has increased their disease: And grievous is the penalty they (incur), because they are false (to themselves). 10 And when it is said to them, "Do not cause corruption on the earth," they say, "We are but reformers." 11 They, certainly, are corrupt but do not realize it. 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 believe'; but when they go privily to their Satans, they say, 'We are with you; we were only mocking.' 14 But God will turn the joke against them and allow them to sink deeper into evil and wander perplexed in their wickedness. 15 Those are they that have bought error at the price of guidance, and their commerce has not profited them, and they are not right-guided. 16 (Their case) is like that of one who kindles a fire and when it grows bright God takes away its light leaving him in darkness (wherein) he cannot see (anything). 17 Deaf, dumb and blind - so they will not return [to the right path]. 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 takes away their sight: whenever it flashes upon them, they walk on, but as soon as darkness falls around them, they stand still. Indeed, if God pleased, He could take away their hearing and their sight: God has power over all things. 20
