I'm unable to understand the assertion here. You said "Ali a.s. Is like Him but He is not like Imam Ali a.s." Nahj al Balagha Sermon 1, Amirul Momineen a.s says: The foremost in religion is the acknowledgment of Him, the perfection of acknowledging Him is to testify Him, the perfection of testifying Him is to believe in His Oneness, the perfection of believing in His Oneness is to regard Him Pure, and the perfection of His purity is to deny Him attributes, because every attribute is a proof that it is different from that to which it is attributed and everything to which something is attributed
