The issue of research in this article is to examine Mulla Sadra's opinion about the predicative attributes of God and whether he is bound to which of the three theories of tashbih, ta`wil and tanzih. The method of this article is librarian and documentary-analytical. The findings of the research show that Sadr al-Muta'allihin, while criticizing the superficialist, also considers the method of philosophers and theologians who use ta`wil in the divine verses to be incorrect. He believes in preserving the originality of the text and opposes those avoiding appearances, and considers the way to achieve this goal to be the doctrine of special monotheism or personal unity and the theory of spirits of meanings. According to this version of particular monotheism, the pure absoluteess of God causes him to be present in every ta`ayyun, and to accept its rulings, and the very pure absoluteness causes him not to be limited to this determination. Although part of this method can be seen in the opinions of a number of mystics, but like other issues of theoretical mysticism that have been highlighted in the transcendent wisdom, its scientific formulation and order is due to Sadra's efforts.
