He [Abu Sa’id] says: "Thus, al-Sadiq—Exalted be His Might—demonstrated that what is not seen is 'cast aside.' Allah cannot be known except through Vision, Beholding, and Existence. For the knowledge of the Eye is 'Existent' (Mawjuda), while the knowledge of the Heart [alone] is 'Non-existent' (Ma’duma)."

It is stated in the well-known reports on the authority of al-Sadiq—Exalted be His Might: "Whoever [claims to have] known Allah through the delusions of hearts (Tawahhum al-Qulub) is a polytheist." (May Allah protect us).
