Payandani (intercession and mediation) is one of the main theological topics in the opening centuries of the Islamic era. Theologians have haddifferent views on this issue, which along with other theological issues, such as determinism and free will, destiny, justice, and the vision of Allah, was widely discussed by Muslim scholars, and fiercely debated by the Mutazilite, the Asharite and later the Shia. The aim of this paper is to discuss in briefthe formation of Payandani and compare the views of the major Islamic schoolson this topic. Moreover, the researcher attempts totrace this subject in Persianpoetry, especially in the poetry of the distinguished Sufi poets of the sixth and seventh centuries, such as Sanai, Attar, Rumi and Saadi.

Hakim Sanāyi Qaznavi (d. 532 AH) who is one of the most influential thinkers and poets of didactic Sufi poetry has always been followed by other poets and mystics of Iran. This paper aims at making a comprehensive study of his Hadiqah and Divān and also intends to explain his opinions about the questions of transcendence or immanence, eternality and contingency, and whether divine Names and attributes are fixed or not and God's intention of creating the universe. The researchers have attempted to compare these opinions with those of other famous theological sects. Therefore, at first the views of the leaders of the Ash'arites, Mu'tazilites, Matoridites, Karrāmits, and 12-Imam Shiites were presented on these issues and then Sanāyi's opinion was analyzed and classified accordingly. This study shows that Sanāyi has used Islamic texts and rational teachings of his era to prove his claims. He has adopted a transcendent and even a negative approach in theology and his positions, contrary to the current views, have been different from those of the Ash'arites, Karāmits, and adherents of hadith, and have been in harmony with those of the Mu'tazilites, Mātoridites, and Shiites.
