This study is about the only surviving copy of Ahmad Hazini's work "Jami'ul-Murshidin" preserved in the Berlin State Library under the number Ms. orient. Oct. 2847. The first information about the work "Jami'ul-Murshidin" was provided by V. Eilers, who prepared the catalog of the manuscript (1968, pp. 274-275). Later, S. Refiu'ddin and N. Hasan (2004, pp. 159-166) conducted a separate study on the work and provided brief information about its sections. However, a comprehensive study on the work has not yet been conducted and published. The work "Jami'ul-Murshidin" consists of four sections written in prose and verse: Jahriyya – Yasawiya, Khajagan – Naqshbandiyya, Kubrawiyya, Eshqiyya – Sidqiyya. The most extensive among the sections is Yasawiya. The book contains various narrations, information about the sheikhs of the sect and some cities. These stories in the work are important in terms of studying the religious-philosophical thought and history of the sects existing in the region.
