ADNAN OKTAR: It has been accounted from the Messenger of Allah (saas): "Soon," in a short time, "a deaf and blind corruption from which the minds of people will be astonished will head towards you so that you would not see a single wise person." That means the minds of people will be gone, says our Prophet (saas), in the End Times. A blind and deaf corruption; for instance Darwinist, materialist movement. The minds of people would go blind, a corruption would head towards you, he says. "At that time people's minds would be lost so that men would be like animals." I mean they will wander around the streets with their mouths open, he says. They will be very foolish, he says. They will not think about the future, nor about the past; they won't think about the Hereafter, they won't think about the Existence of Allah. They will be after such crude needs like eating, drinking, intercourse and sleeping. Look; "Men would be like animals, their minds would be lost." What would an animal do? Eat, drink, reproduce, sleep; that is it and wander around.   
"As a matter of fact, no one could find a shelter from that corruption. No one would be able to have the strength to say things like "why?" "How?" "Enough is enough"."
Because they will not have their minds in the right place, people, many of them, a great many of them would not be able to say why is this happening, why is that happening, enough is enough, let this be corrected, let Islam rule the world.  "Corruption will start in one place before it ends elsewhere. Everyone would think that they are on the right path," says our Prophet (saas). So he says people will assume that they are on the right path, that they are very wise, very to the point and assume that they are the best group ever. He says that the corruption will start in one place, while you would assume that it ended in another. "In the end until an individual from my family -Hazrat Mahdi (pbuh)- appears, there will be no house left that corruption did not enter." So he says that corruption will enter everyone's houses.
