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 a disease, and Allah increaseth their disease. A painful doom is theirs because they lie. 10 When they are told not to commit corruption in the land, they reply, "We are only reformers". 11 Unquestionably, it is they who are the corrupters, but they perceive [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 To the believers they declare belief and, in secret to their own devils, they say, "We were only mocking". 14 [But] Allah mocks them and prolongs them in their transgression [while] they wander blindly. 15 They are indeed those who bartered away good guidance for error and gained nothing from the deal, nor found the right way. 16 Their example is like one who kindled a fire, and when it lit all around him, Allah took away their light and left them in darkness. They could not see. 17 Deaf, dumb, blind - and they cannot turn back. 18 or as a cloudburst out of heaven in which is darkness, and thunder, and lightning -- they put their fingers in their ears against the thunderclaps, fearful of death; and God encompasses the unbelievers; 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
