I heard Allah say: 

Ali bin Abi Taleb is My decisive proof on My creatures.  He is My light in My land and he is the trustworthy caretaker of My knowledge.  I will not allow those who know him to enter Hell, even if they disobey Me.  And I will not allow those who deny him to enter Paradise, even if they obey Me.
