And of mankind are some who say: we believe in Allah and in the Last Day: whereas they are not believers. 8 They (try to) deceive God and those who believe, yet deceive none but themselves although they do not know. 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 they are told, "Do not spread corruption on earth," they answer, "We are but improving things!" 11 Unquestionably, it is they who are the corrupters, but they perceive [it] not. 12 And when it is said unto them: believe as the people believe, they say: shall we believe as the foolish believe? are not they indeed the foolish? But they know not. 13 And when they meet those who have believed, they say: We believe. And when they are alone with their satans, they say: verily we are with you, we were but mocking. 14 God shall mock them, and shall lead them on blindly wandering in their insolence. 15 These are they who purchased error for guidance, but their traffic profited not, nor have they ever become guided. 16 Their parable is that of people who kindle a fire: but as soon as it has illumined all around them, God takes away their light and leaves them in utter darkness, wherein they cannot see: 17 deaf, dumb, and blind: they will never return [to the right path]. 18 Or [the parable] of a violent cloudburst in the sky, with utter darkness, thunder and lightning: they put their fingers into their ears to keep out the peals of thunder, in terror of death; but God encompasses [with His might] all who deny the truth. 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
