And there are some people who say: We believe in Allah and the last day; and they are not at all believers. 8 They would deceive God and those who have attained to faith - the while they deceive none but 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 When it is said to them, 'Do not corruption in the land', they say, 'We are only ones that put things right.' 11 Now surely they themselves are the mischief makers, but they do not perceive. 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 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 will throw back their mockery on them, and give them rope in their trespasses; so they will wander like blind ones (To and fro). 15 Those are the ones who have purchased error [in exchange] for guidance, so their transaction has brought no profit, nor were they guided. 16 They are like a man who kindles a fire, and when its glow has illumined the air God takes away their light leaving them in the dark where they will not be able to see. 17 They are deaf; they are dumb; they are blind so they will not return (to the right way). 18 Or [the parable] of a violent cloudburst in the sky, with utter darkness, thunder and lightning: they put their fingers into their ears to keep out the peals of thunder, in terror of death; but God encompasses [with His might] all who deny the truth. 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
