Seyyed Mohammad Bagher Tabatabaei Yazdi is regarded as one of the great scholars of the thirteenth century AH. God-given talent and, intelligence, the multitude of travel, poetic talent, and diversity and multiplicity of verse and prose writings in Arabic and Persian are among his personality traits."Firoozjat-e Toosiyeh: A Commentary on Razavieh Sermon" is one of his major works, which includes literary, philosophical, theological, ethical, political, and mystical values, and in which Treaty of Malek Ashtar and part of the letter of Imam Sadeq (pbuh) to Najashi were cited in the introduction. In this work written two decades before the events of the Constitution, the author made, in a temperate manner, important recommendations to Nasser al-Din Shah's on justice, tact and discretion when dealing with people, following the religious authority, respecting the scholars and Sadat, and improving the affairs, and He provided a rational-reasoning description on Towhidiyeh Sermon delivered by Imam Reza (pbuh). Firoozjat has partly scientific style and partly literarily technical style.The rhythmic prose is interspersed with the verses, hadiths, poems, proverbs, and attractive historical anecdotes.No research has been done so far on Firoozjat. The author has been affected by the Saadi, Jami, and Naraghi in the apparent structure of this work, and by Sadrol-moteallehin in philosophical and theological opinions.
