There are some people who say: 'We believe in Allah and the Last Day, 'yet they are not believers. 8 They wish to deceive Allah and the believers; and in fact they deceive none except themselves and they do not have any understanding. 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 Verily! They are the ones who make mischief, but they perceive not. 12 And when it is said to them, "Believe as the people have believed," they say, "Should we believe as the foolish have believed?" Unquestionably, it is they who are the foolish, but they know [it] not. 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 and blind; and they are not to return. 18 Or their case is like that of heavy rain pouring down from the clouds, accompanied by darkness, thunder and lightning; they thrust their fingers in their ears at the sound of thunderclaps for fear of death. God thus encompasses those who deny the truth. 19 the lightning wellnigh snatches away their sight; whensoever it gives them light, they walk in it, and when the darkness is over them, they halt; had God willed, He would have taken away their hearing and their sight. Truly, God is powerful over everything. 20
