BACKGROUND AND OBJECTIVES: The book of Serr al-Asrar is a valuable Ashura book that has been neglected in Persian history and literature. The book of Serr al-Asrar is one of these precious works. Serr al Asrar is the name of a historical-literary book in Persian language, which was completed after the death of the author, with the efforts of his son. Sheikh Abdul Rahim Jalili-Kermanshahi is one of the famous writers of the Nasser period, who has valuable but less known works. His son, Sheikh Mohammad Hadi Jalili, was also one of the great writers of his time who finished his father"s Ashurai book. Each of the narrative types has its own stylistic features, and their stylistic analysis leads to a better understanding of these works. The purpose of conducting this research is to introduce this historical-literary work and examine its three aspects: linguistic, intellectual and literary.

METHODOLOGY: This article is based on library studies in a descriptive-analytical way.

FINDINGS: The findings show that the book of Serr al-Asrar has the same writing style despite having two authors. Despite the Arabic knowledge of the authors, the type of narration requires simple language. Therefore, while showing their knowledge of Arabic, the authors adhere to simple writing, and this issue has given the work different features and indicators. Therefore, the stylistic reading of this work shows a clear understanding of its multiple levels.

CONCLUSION: This work is a historical and realistic narrative, which, in addition to its linguistic and intellectual highlights, has acquired a literary flavor by mixing with rhetorical tricks. The prose of this book is intermediate and there are prominent features of a single language in the language of both authors. In terms of thought, despite the intellectual unity of both authors, themes are raised that show their intellectual independence. From a literary point of view, it is necessarily mixed with rhetorical techniques and more than having an aesthetic purpose, it serves to clarify and depict the atmosphere of events, narrative characters, and the feelings and thoughts of the writers.
