Believing in the great human and religious grandure of khalifa Ali ra is not mutually exclusive with the belief in Allah swt and the prophet pbuh. Muslims should respect and accept the grandure of all khalifas: Abu Baker, Omar, Uthman, and Ali and all other companions raa of the prophet pbuh. But none of them is divine, not even the prophet himselft is divine. The only one who can respond and reward supplication and prayer is Allah and is thus the only one to be asked and invoked; no one else. And as sister jabba told u already, only God judges who goes to hell and who does not.
