Corruption:
In short, at this time, mankind was on a suicidal course. Man had forgotten his Creator and was oblivious of himself, his future, and his destiny. He had lost the ability to distinguish between good and evil, and what is beautiful and what is ugly. Throughout vast regions no one was concerned with religion at all and no one worshipped his Lord without associating something with Him. Allah Almighty spoke the truth when He said: 'Corruption has appeared in the land and sea through what the hands of People have earned, that He may let them taste some part of that which they have done, that perhaps they will return.' (30:41)
