There are some people who say: 'We believe in Allah and the Last Day, 'yet they are not 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 sickness, and God has increased their sickness, and there awaits them a painful chastisement for that they have cried lies. 10 And when it is said to them: "Make not mischief on the earth," they say: "We are only peacemakers." 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 When they meet the faithful they say: "We believe;" but when alone with the devils (their fellows), they say: "We are really with you; we were joking." 14 God shall mock them, and shall lead them on blindly wandering in their insolence. 15 These are they who have bartered Guidance for error: But their traffic is profitless, and they have lost true direction, 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 They are deaf, dumb, and blind, so they return not (to the Right Path). 18 Or like rain pouring from the sky which hides within it darkness, thunder and lightning. They thrust their fingers into their ears for safety against noise and death. But God surrounds those who believe not from all sides. 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
