Persian language in Siberia: Introduction of three Persian manuscripts written by Dolatshah Hosseini Espijabi (Burhān Al-Dhākirīn, Khawāṣ Jawīhir Aḥjār, al-Risāleh al-Qudsiyyeh al-Sami'iyyeh)

 For many years, scholars and some research institutes in Russia have conducted valuable research on Islamic texts, especially Sufism in Russia. A collection of three Persian treatises of Burhan Al-Dhākirīn, Khawāṣ Jawīhir Aḥjār and al-Risāleh al-Qudsiyyeh al-Sami'iyyeh, which was published under the general title of Burhan al-Dhakerin in the form of a transcript with an analytical introduction and Russian translation, in 2020, by the Ibn Sina Foundation, is one example of these works. The present article is a note introducing the three treatises published in this collection. The two treatises of Burhān al-Dhākirīn and Khawāṣ Jawīhir Aḥjār are in a handwriting collection, and the treatise Al-Risala al-Qudsiya al-Sama'iyyah belongs to another manuscript. All three treatises appear to be written by Dolatshah ibn Abd al-Wahhab al-Husseini al-Spijabi who was one of the Sheikhs of Yasawi Sufi way. However, the author's name is not mentioned in the treatise on Khawāṣ Jawīhir Aḥjār. The analytical introduction to the collection was written by Dr. Alfrid Kashafovich Bustanov, a professor at the University of Amsterdam, and the Russian translation of the text was written by Dr. Evgenia Nikitenko, a scholar in the field of Iranian research and professor of Persian at Moscow State University of Economics. The 240-page collection of transliterations of Burhan al-Dhakerin, including the facsimile manuscript at the end of the book, has been published in a circulation of seven hundred copies, with the scientific support and supervision of the Russian Ibn Sina Studies Foundation and Sadra Moscow Publishing.
