There are some people who say: 'We believe in Allah and the Last Day, 'yet they are not believers. 8 They think to beguile Allah and those who believe, and they beguile none save themselves; but they perceive not. 9 There is a sickness in their hearts which Allah has increased. For them there is a painful punishment because they 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 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 To the believers they declare belief and, in secret to their own devils, they say, "We were only mocking". 14 Allah shall pay them back their mockery, and He leaves them alone in their inordinacy, blindly wandering on. 15 These are the people who purchased error in exchange of guidance – so their bargain did not profit them, and they did not know how to trade. 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 -- so they shall not return; 18 Or like abundant rain from the cloud in which is utter darkness and thunder and lightning; they put their fingers into their ears because of the thunder peal, for fear of death, and Allah encompasses the unbelievers. 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
