Some people say, "We believe in God and the Day of Judgment," but they are not true believers. 8 They seek to deceive God and the believers, but they only deceive themselves, though they do not realize it. 9 A sickness exists in their hearts to which God adds more sickness. Besides this, they will suffer a painful punishment as a result of the lie which they speak. 10 And when they are told, "Do not spread corruption on earth," they answer, "We are but improving things!" 11 Oh, verily, it is they, they who are spreading corruption but they perceive it not? 12 And when it is said to them, “Believe as the others believe”, they say, “Shall we believe as the foolish believe?” It is they who are the fools, but they do not know. 13 When they meet those who believe, they say, 'We, too believe.' But when they are alone with their devils, they say to them: 'We follow none but you, we were only mocking 14 [But] Allah mocks them and prolongs them in their transgression [while] they wander blindly. 15 Such are those who have taken misguidance in exchange for guidance; but their bargain does not profit them, nor have they found true guidance. 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 Deaf, dumb and blind - so they will not return [to the right path]. 18 Or it is like that of a rain storm with darkness, thunder, and lightning approaching. They cover their ears for fear of thunder and death. God encompasses those who deny His words. 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
