And there are some who, though they say: "We believe in God and the Last Day," (in reality) do not believe. 8 They (try to) deceive God and those who believe, yet deceive none but themselves although they do not know. 9 In their hearts is a disease; and Allah has increased their disease: And grievous is the penalty they (incur), because they are false (to themselves). 10 And when they are told, "Do not spread corruption on earth," they answer, "We are but improving things!" 11 Lo! verily it is they who are the corrupters, and yet they perceive not. 12 When it is said to them: "Believe as the others believe:" They say: "Shall we believe as the fools believe?" Nay, of a surety they are the fools, but they do not know. 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 (Little do they realize that) Allah is mocking at them. He gives them rope enough, and they wander on and on blindly in their mischief and rebellion. 15 They have traded guidance for error, but their bargain has had no profit and they have missed the 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, blind; wherefore they will not return. 18 Or [it is] like a rainstorm from the sky within which is darkness, thunder and lightning. They put their fingers in their ears against the thunderclaps in dread of death. But Allah is encompassing of the disbelievers. 19 The lightning well-nigh takes away their sight; whenever it gives them light, they advance therein, and whenever darkness falls around them, they stand still. And if God so willed, He could indeed take away their hearing and their sight: for, verily, God has the power to will anything. 20
