And there are some people who say: We believe in Allah and the last day; and they are not at all believers. 8 They thus try to deceive Allah and the Believers, but they succeed in deceiving none except themselves and they realize it not. 9 In their hearts is a disease which Allah has increased all the more and a painful doom is in store for them for the lie they utter. 10 And when they are told, "Do not spread corruption on earth," they answer, "We are but improving things!" 11 They, certainly, are corrupt but do not realize it. 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 those who believe, they say: "We believe;" but when they are alone with their evil ones, they say: "We are really with you: We (were) only jesting." 14 Allah mocks at them and gives them increase in their wrong-doings to wander blindly. 15 [for] it is they who have taken error in exchange for guidance; and neither has their bargain brought them gain, nor have they found guidance [elsewhere]. 16 Their parable is that of people who kindle a fire: but as soon as it has illumined all around them, God takes away their light and leaves them in utter darkness, wherein they cannot see: 17 Deaf, dumb and blind - so they will not return [to the right path]. 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 The lightning almost takes away their sight: whenever it flashes upon them, they walk on, but as soon as darkness falls around them, they stand still. Indeed, if God pleased, He could take away their hearing and their sight: God has power over all things. 20
