And there are some who, though they say: "We believe in God and the Last Day," (in reality) do not believe. 8 They wish to deceive Allah and the believers; and in fact they deceive none except themselves and they do not have any understanding. 9 In their hearts is disease, and so God lets their disease increase; and grievous suffering awaits them because of their persistent lying. 10 And when it is said to them, "Do not cause corruption on the earth," they say, "We are but reformers." 11 Lo! verily it is they who are the corrupters, and yet they perceive not. 12 When asked to believe as others do, they say: "Should we believe like fools?" And yet they are the fools, even though they do not know. 13 To the believers they declare belief and, in secret to their own devils, they say, "We were only mocking". 14 God shall mock them, and shall lead them on blindly wandering in their insolence. 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 They are like those who kindled a fire, and when it lighted up all around them, God took away their sight and left them in utter darkness, unable to see -- 17 They are deaf, blind, and dumb and cannot regain their senses. 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 snatches away their sight, whenever it flashes upon them they walk on, but as soon as it darkens they stand still. Indeed, if Allah willed, He could take away their sight and hearing. Allah has power over all things. 20
