And there are some people who say: We believe in Allah and the last day; and they are not at all believers. 8 Fain would they deceive Allah and those who believe, but they only deceive themselves, and realise (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 they are told, "Do not spread corruption on earth," they answer, "We are but improving things!" 11 Truly, they are the workers of corruption but they are not aware. 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 believe.' But when they are alone with their devils, they say to them: 'We follow none but you, we were only mocking 14 God will requite them for their mockery, and draw them on, for a while, to wander blindly in their insolence. 15 These are they who have purchased error for guidance, so their commerce was profitless. And they were not guided. 16 Their parable is like the parable of one who kindled a fire, but when it had illumined all around him, Allah took away their light, and left them in utter darkness-- they do not see. 17 They are deaf, blind, and dumb and cannot regain their senses. 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
