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, which God has increased. They will have a painful punishment, because they have been lying. 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 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 Allah shall pay them back their mockery, and He leaves them alone in their inordinacy, blindly wandering on. 15 These are they who have purchased error for guidance, so their commerce was profitless. And they were not guided. 16 They are like a man who kindles a fire, and when its glow has illumined the air God takes away their light leaving them in the dark where they will not be able to see. 17 deaf, dumb, and blind: they will never return [to the right path]. 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 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
