And there are people who say: "We do believe in God and the Last Day," the while they do not [really] believe. 8 They would deceive Allah and those who believe, whereas they deceive not save themselves, and they perceive not. 9 Sick are their hearts, and God adds to their malady. For them is suffering for they lie. 10 And when they are told, "Do not spread corruption on earth," they answer, "We are but improving things!" 11 Of a surety, they are the ones who make mischief, but they realise (it) not. 12 And when it said unto them: believe even as mankind have believed, they say: shall we believe even as the fools have believed? Lo! verily it is they who are the fools; and yet they know not. 13 When they meet those who believe, they say: "We believe;" but when they are alone with their evil ones, they say: "We are really with you: We (were) only jesting." 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 Such are those who have taken misguidance in exchange for guidance; but their bargain does not profit them, nor have they found true guidance. 16 (Their case) is like that of one who kindles a fire and when it grows bright God takes away its light leaving him in darkness (wherein) he cannot see (anything). 17 Deaf, dumb, and blind, they shall never return. 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 It seems the lightning may snatch away their sight from them; whenever it flashes they walk in it, and when it darkens they stand still; if Allah willed, He could take away their hearing and their sight; indeed Allah is Able to do all things. 20
