And of mankind are some who say: We believe in Allah and the Last Day, when they believe not. 8 They seek to deceive God and the believers, but they only deceive themselves, though they do not realize it. 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 they are told not to commit corruption in the land, they reply, "We are only reformers". 11 Yet they are surely mischief-mongers, even though they do not know. 12 And when it is said to them, "Believe sincerely as the other people have believed", they reply, "Should we believe as fools have believed?" Beware! they themselves are the fools, but they know it not. 13 And when they meet those who have attained to faith, they assert, "We believe [as you believe]"; but when they find themselves alone with their evil impulses, they say: "Verily, we are with you; we were only mocking!" 14 Allah mocks at them and gives them increase in their wrong-doings to wander blindly. 15 They are indeed those who bartered away good guidance for error and gained nothing from the deal, nor found the right way. 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 They are deaf; they are dumb; they are blind so they will not return (to the right way). 18 or as a cloudburst out of heaven in which is darkness, and thunder, and lightning -- they put their fingers in their ears against the thunderclaps, fearful of death; and God encompasses the unbelievers; 19 the lightning wellnigh snatches away their sight; whensoever it gives them light, they walk in it, and when the darkness is over them, they halt; had God willed, He would have taken away their hearing and their sight. Truly, God is powerful over everything. 20
