Zoroastrians’ written legacy in the New Persian is a treasure full of religious works in the Persian literature, but little attention has been paid to it. Gradually from the 4th century onward, these texts were created from reproduction of Avestan and Pahlavi texts, and hundreds of treatises in the fields of jurisprudence, traditions, interpretation, mythology, history, kalam, literature, narration, linguistics, astronomy, etc. are left by the Zoroastrianclergy. Kalamis one of the oldest topics in the Zoroastrian Persian literature thanks to the relations between Zoroastrians and the Islamic society. The most important Zoroastrian kalam text in the New Persian is the Islamic Scholars Treatise. Though this work has drawn the attention of the researchers from the early 19th century, its remnants have yet to be known fully. There are two editions of this treatise. By assessing what is left from the above said treatise, this study seeks to present a suggestion for rewriting and compilation of dispersed pieces different selections based on the textual and thematic evidence.
