Imam Sadeq (PBUH) said:
The assets of the disbelievers are the three of the drunkenness, the caterpillar, and the grace, as for the drifting, then the peace be upon him, when it is forbidden by the tree from the tree. I am on the authority of Apple, when he was commanded by the prostration of Adam, I was arrogant, and the envy is our son Adam, as one of them was killed.
The roots of disbelief are of three species: greed, arrogance and jealousy, but greed is the same as that overwhelmed by Adam and forced him to eat that tree, if God had forbidden him to approach that tree. But arrogance and selfishness is the same as the devil forbidden to prostrate to Adam, and he did not prostrate Adam for arrogance, but jealousy is to make two children enemies as far as one of them. He killed his brother.
