Adam’s Mistake Was The Cause Of This World’s Creation?
The whole plan of creation of Adam was announced before the event of Satan’s disobedience. God told that he was going to send a Khalifah to the earth. The angel shared their reservation that he might spread corruption. Then God said He knows what the angels do not. The angels perceived the mischievousness of man before the intervention of Satan. Satan is noting but a stimulus to invite man to evil and that evil along with piety resides in man’s nature. The test did not start with the devil’s disobedience. it was all well there already.
