And there are some people who say: We believe in Allah and the last day; and they are not at all believers. 8 They deceive God and the believers. However, they have deceived no one but themselves, a fact of which they are not aware. 9 In their hearts is a disease, which God has increased. They will have a painful punishment, because they have been lying. 10 When it is said to them, 'Do not corrupt in the land,' they reply, 'We are only reformers.' 11 Unquestionably, it is they who are the corrupters, but they perceive [it] 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 And when they meet those who have attained to faith, they assert, "We believe [as you believe]"; but when they find themselves alone with their evil impulses, they say: "Verily, we are with you; we were only mocking!" 14 Allah mocks at them and gives them increase in their wrong-doings to wander blindly. 15 Such are those who barter away guidance for error, their trade did not profit (them), nor are they guided. 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, so they will not turn back. 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
