The religion of the Ahl al-Haqq believes in the manifest agency of God. The great men of the Ahl al-Haqq have interpreted ontology on this basis. This article has explained and examined the philosophical-mystical ontological perspective of Nowruz Ali Sorani, who is considered as one of the leaders of the Ahl al-Haqq. Since Nowruz was influenced by the aesthetic and epistemological perspective of the wisdom of illumination, Sufism, and mysticism, he has used philosophical terms and concepts more than other leaders of this tribe in expressing ontology. Due to its complexity and mystery, Nowruz Ali's book has not been translated or interpreted so far, and it has not been the subject of scientific and problem-oriented research. This article has answered the question: In what cases is Nowruz Ali Sorani's ontological perspective influenced by Sufism and mysticism? Nowruz's borrowing of concepts and terms from mystics and enlightened philosophers has brought his approach to the mystical and enlightened approach in expressing ontology issues. Nevertheless, the foundation of the worldview of the Ahl al- Hqq is clearly and undeniably evident in the words of Nowruz Ali. This article uses a descriptive-analytical method and decodes and analyzes the content to explain and examine Nowruz Ali's epistemological view of existence. The goals of this article are to use philosophy and mysticism to find equivalents for the terms in Nowruz Ali's notebook, to integrate and organize the scattered material in his collection of poems to recognize, explain and analyze Nowruz Ali's thought on ontology. The approach of going beyond the different opinions and views of the Sorani poet is another goal of this article.
