Some people say, "We believe in God and the Day of Judgment," but they are not true believers. 8 They [think to] deceive Allah and those who believe, but they deceive not except themselves and perceive [it] not. 9 In their hearts is a disease, so Allah has increased their disease; and for them is a painful punishment, because of their lies. 10 When it is said to them, 'Do not corruption in the land', they say, 'We are only ones that put things right.' 11 Truly, they are the workers of corruption but they are not aware. 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 And when they meet those who believe, they say: "We believe," but when they are alone with their Shayatin (devils - polytheists, hypocrites, etc.), they say: "Truly, we are with you; verily, we were but mocking." 14 God will requite them for their mockery, and draw them on, for a while, to wander blindly in their insolence. 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, so they will not turn back. 18 Or like a rainstorm from the sky, wherein is darkness, thunder and the flash of lightning. They thrust their fingers in their ears by reason of the thunder-claps, for fear of death, Allah encompasseth the disbelievers (in His guidance, His omniscience and His omnipotence). 19 The lightning all but snatches away their sight; every time the light (Helps) them, they walk therein, and when the darkness grows on them, they stand still. And if Allah willed, He could take away their faculty of hearing and seeing; for Allah hath power over all things. 20
