And of mankind are some who say: we believe in Allah and in the Last Day: whereas they are not believers. 8 They would deceive Allah and those who believe, whereas they deceive not save themselves, and they perceive not. 9 In their hearts is a disease, and Allah increaseth their disease. A painful doom is theirs because they lie. 10 When it is said to them: "Make not mischief on the earth," they say: "Why, we only Want to make peace!" 11 Unquestionably, it is they who are the corrupters, but they perceive [it] not. 12 And when it is said to them, "Believe sincerely as the other people have believed", they reply, "Should we believe as fools have believed?" Beware! they themselves are the fools, but they know it not. 13 And when they meet those who believe, they say, "We believe"; but when they are alone with their evil ones, they say, "Indeed, we are with you; we were only mockers." 14 Allah mocks at them and gives them increase in their wrong-doings to wander blindly. 15 [for] it is they who have taken error in exchange for guidance; and neither has their bargain brought them gain, nor have they found guidance [elsewhere]. 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 They are deaf, dumb, and blind, so they return not (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 Verily the lightning could snatch away their eyes. When it flashes forth they walk in its flare. When darkness returns they stand still. And if the Lord wills so He could take away their hearing and sight; surely God is all-powerful. 20
