And of mankind are some who say: we believe in Allah and in the Last Day: whereas they are not believers. 8 They [think to] deceive Allah and those who believe, but they deceive not except themselves and perceive [it] not. 9 A sickness exists in their hearts to which God adds more sickness. Besides this, they will suffer a painful punishment as a result of the lie which they speak. 10 When it is said to them, 'Do not corrupt in the land,' they reply, 'We are only reformers.' 11 Lo! verily it is they who are the corrupters, and yet they perceive not. 12 When it is said to them, 'Believe as the people believe', they say, 'Shall we believe, as fools believe?' Truly, they are the foolish ones, but they do not know. 13 When they meet those who believe, they say: "We believe;" but when they are alone with their evil ones, they say: "We are really with you: We (were) only jesting." 14 Allah mocketh back at them, and letteth them in their exorbitance wander bewildered. 15 These are the people who purchased error in exchange of guidance – so their bargain did not profit them, and they did not know how to trade. 16 Their parable is that of people who kindle a fire: but as soon as it has illumined all around them, God takes away their light and leaves them in utter darkness, wherein they cannot see: 17 Deaf, dumb, blind; wherefore they will 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 well-nigh snatcheth away their sight; whensoever it flasheth on them, they walk therein, and when it becometh dark unto them, they stand still. And had Allah willed He would of a surety have taken away their hearing and their sights; verily Allah is over everything potent. 20
