There are some people who say: 'We believe in Allah and the Last Day, 'yet they are not believers. 8 They thus try to deceive Allah and the Believers, but they succeed in deceiving none except themselves and they realize it not. 9 In their hearts is a disease; and Allah has increased their disease: And grievous is the penalty they (incur), because they are false (to themselves). 10 When they are told not to commit corruption in the land, they reply, "We are only reformers". 11 Of a surety, they are the ones who make mischief, but they realise (it) not. 12 And when it is said to them, “Believe as the others believe”, they say, “Shall we believe as the foolish believe?” It is they who are the fools, but they do not know. 13 And when they fall in with those who believe, they say: We believe; but when they go apart to their devils they declare: Lo! we are with you; verily we did but mock. 14 Allah will throw back their mockery on them, and give them rope in their trespasses; so they will wander like blind ones (To and fro). 15 These are they who purchase error at the price of guidance, so their commerce doth not prosper, neither are they guided. 16 They are like those who kindled a fire, and when it lighted up all around them, God took away their sight and left them in utter darkness, unable to see -- 17 deaf, dumb, blind -- so they shall not return; 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 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
