Of the people there are some who say: "We believe in Allah and the Last Day;" but they do not (really) believe. 8 They deceive God and the believers. However, they have deceived no one but themselves, a fact of which they are not aware. 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 And when it is said to them, "Do not cause corruption on the earth," they say, "We are but reformers." 11 Lo! verily it is they who are the corrupters, and yet they perceive not. 12 And when it is said to them: Believe as the people believe, they say: Shall we believe as the fools believe? Now surely they themselves are the fools, but they do not know. 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] Allah mocks them and prolongs them in their transgression [while] they wander blindly. 15 These are they who have bartered Guidance for error: But their traffic is profitless, and they have lost true direction, 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, blind -- so they shall not return; 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 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
