And of the people are some who say, "We believe in Allah and the Last Day," but 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 disease, and so God lets their disease increase; and grievous suffering awaits them because of their persistent lying. 10 And when it is said to them: "Make not mischief on the earth," they say: "We are only peacemakers." 11 but it is they who are really causing corruption, though they do not realize it. 12 When it is said to them, 'Believe as the people believe', they say, 'Shall we believe, as fools believe?' Truly, they are the foolish ones, 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 will mock at them and prolong them in sin, blundering blindly. 15 Such are those who barter away guidance for error, their trade did not profit (them), nor are they guided. 16 Their example is like that of one who kindled a fire; and when it lit up all that was around it, Allah took away their light and left them in darkness, unable to see anything. 17 Deaf, dumb and blind - so they will not return [to the right path]. 18 Or, like (those who, under) a cloudburst from the sky with darkness, thunder and lightning, they thrust their fingers in their ears at the sound of every thunderclap for fear of death, and Allah encompasses the unbelievers. 19 The lightning well-nigh takes away their sight; whenever it gives them light, they advance therein, and whenever darkness falls around them, they stand still. And if God so willed, He could indeed take away their hearing and their sight: for, verily, God has the power to will anything. 20
