There are some who say, "We believe in God and the Last Day," yet 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 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 And when they are told, "Do not spread corruption on earth," they answer, "We are but improving things!" 11 Verily! They are the ones who make mischief, but they perceive not. 12 When they are told to believe as everyone else does, they say, "Should we believe as fools do?" In fact, they themselves are fools, but they do not know it. 13 And when they meet those who believe, they say: We believe; and when they are alone with their Shaitans, they say: Surely we are with you, we were only mocking. 14 God will requite them for their mockery, and will leave them for a while in their overweening arrogance, blindly stumbling to and fro: 15 These are the people who have bartered away Guidance for error, but this is a profitless bargain that they have made, and they are not at all on the right way. 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, and blind: they will never return [to the right path]. 18 Or [it is] like a rainstorm from the sky within which is darkness, thunder and lightning. They put their fingers in their ears against the thunderclaps in dread of death. But Allah is encompassing of the disbelievers. 19 The lightning all but snatches away their sight; every time the light (Helps) them, they walk therein, and when the darkness grows on them, they stand still. And if Allah willed, He could take away their faculty of hearing and seeing; for Allah hath power over all things. 20
