Some people say, "We believe in God and the Day of Judgment," but they are not true believers. 8 They think to beguile Allah and those who believe, and they beguile none save themselves; but they perceive not. 9 In their hearts is a disease, so Allah has increased their disease; and for them is a painful punishment, because of their lies. 10 When they are told not to commit corruption in the land, they reply, "We are only reformers". 11 Verily! They are the ones who make mischief, but they perceive not. 12 When it is said to them: 'Believe as (other) people believe,' they reply, 'Are we to believe as fools believe?' It is they who are the fools, if only they knew! 13 When they meet those who believe, they say, "We believe." But when they are alone with their evil leaders, they say, "We are really with you; we were only mocking." 14 Allah will mock at them and prolong them in sin, blundering blindly. 15 These are they who purchase error at the price of guidance, so their commerce doth not prosper, neither are they guided. 16 They are like a man who kindles a fire, and when its glow has illumined the air God takes away their light leaving them in the dark where they will not be able to see. 17 They are deaf; they are dumb; they are blind so they will not return (to the right way). 18 Or like a rainstorm from the sky, in which are darkness, thunder and lightning; they thrust their fingers in their ears due to the thunderclaps, fearing death; and Allah has the disbelievers encompassed. 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
