Some people say, "We believe in God and the Day of Judgment," but they are not true 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 disease, so Allah has increased their disease; and for them is a painful punishment because they [habitually] used to lie. 10 When it is said to them, 'Do not corruption in the land', they say, 'We are only ones that put things right.' 11 Are not they indeed the mischief-makers? 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 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 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 They are deaf, dumb, and blind, so they return not (to the Right Path). 18 Or [the parable] of a violent cloudburst in the sky, with utter darkness, thunder and lightning: they put their fingers into their ears to keep out the peals of thunder, in terror of death; but God encompasses [with His might] all who deny the truth. 19 The lightning almost takes away their vision. When the lightning brightens their surroundings, they walk and when it is dark, they stand still. Had God wanted, He could have taken away their hearing and their vision. God has power over all things. 20
