And of mankind are some who say: We believe in Allah and the Last Day, when they believe not. 8 They [think to] deceive Allah and those who believe, but they deceive not except themselves and perceive [it] not. 9 A sickness exists in their hearts to which God adds more sickness. Besides this, they will suffer a painful punishment as a result of the lie which they speak. 10 And when they are told, "Do not spread corruption on earth," they answer, "We are but improving things!" 11 Now surely they themselves are the mischief makers, but they do not perceive. 12 When it is said to them, 'Believe as the people believe', they say, 'Shall we believe, as fools believe?' Truly, they are the foolish ones, but they do not know. 13 And when they meet those who believe, they say: We believe; and when they are alone with their Shaitans, they say: Surely we are with you, we were only mocking. 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 Deaf, dumb and blind - so they will not return [to the right path]. 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 almost snatches away their sight, whenever it flashes for them, they walk therein, and when darkness covers them, they stand still. And if Allah willed, He could have taken away their hearing and their sight. Certainly, Allah has power over all things. 20
