And of mankind are some who say: we believe in Allah and in the Last Day: whereas they are not believers. 8 They (try to) deceive God and those who believe, yet deceive none but themselves although they do not know. 9 In their hearts is a disease which Allah has increased all the more and a painful doom is in store for them for the lie they utter. 10 And when they are told, "Do not spread corruption on earth," they answer, "We are but improving things!" 11 Of a surety, they are the ones who make mischief, but they realise (it) 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, too, are believers", but when they privily meet their evil geniuses, they say, "Indeed we are with you: we are only mocking at these people". 14 But God will turn the joke against them and allow them to sink deeper into evil and wander perplexed in their wickedness. 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 Deaf, dumb and blind; and they are not to return. 18 Or like rain pouring from the sky which hides within it darkness, thunder and lightning. They thrust their fingers into their ears for safety against noise and death. But God surrounds those who believe not from all sides. 19 The lightning almost takes away their sight; whenever it shines on them they walk in it, and when it becomes dark to them they stand still; and if Allah had pleased He would certainly have taken away their hearing and their sight; surely Allah has power over all things. 20
