There are some people who say: 'We believe in Allah and the Last Day, 'yet they are not believers. 8 Fain would they deceive Allah and those who believe, but they only deceive themselves, and realise (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 it is said to them, "Do not cause corruption on the earth," they say, "We are but reformers." 11 but it is they who are really causing corruption, though they do not realize it. 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 leaders, they say, "We are really with you; we were only mocking." 14 [But] Allah mocks them and prolongs them in their transgression [while] they wander blindly. 15 These are they who have purchased error for guidance, so their commerce was profitless. And they were not guided. 16 The likeness of them is as the likeness of a man who kindled a fire, and when it lit all about him God took away their light, and left them in darkness unseeing 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 The lightning almost takes away their vision. When the lightning brightens their surroundings, they walk and when it is dark, they stand still. Had God wanted, He could have taken away their hearing and their vision. God has power over all things. 20
