Shaykh Muhammad Osman Siraceddin (K.S.) was born in the village of Biyara, affiliated with the Ottoman province of Halabja, in the year 1314 AH / 1896 CE. Coming from a family rooted in religious scholarship and the Sufi tradition, he received a religious education from an early age. He studied Arabic and partly Persian, with a strong command of Arabic literature. His formal education was conducted at the madrasas of Biyara and Durud.
Siraceddin developed a particular interest in Qur’anic recitation and studied the rules of tajwid under the prominent Egyptian reciter, Shaykh Mustafa Ismail. He progressed in the fields of Islamic jurisprudence (fiqh), Sharia, and Sufism. Following the death of his father, he assumed the role of spiritual guide (murshid) and continued scholarly activities in various regions, providing assistance to the needy and organizing the functions of the khanqah (dervish lodge).
Until 1958, Siraceddin resided in Biyara. Due to political developments, he later migrated to Iran, where he expanded his educational and religious efforts. Numerous scholars and teachers gathered around him during this period. He played a leading role in the establishment of large madrasas, especially in Turkmen-populated areas. One such institution, the Yarjan Madrasa, was built to accommodate 400–500 students. In the Devrud region, additional madrasas were established, with student provisions financed through endowment revenues.
His influence extended beyond the region, reaching Europe and North America. He received many letters from abroad, including a poem written by a disciple from Canada as an expression of devotion, which has been documented as a notable example of his spiritual reach.
In the 1970s, after political shifts in Iran, he returned to his birthplace. During the Iran-Iraq War, he moved to Baghdad, where he continued to engage in charitable activities, offering assistance to the sick and poor.
In 1990, Shaykh Siraceddin migrated to Turkey and resumed his guidance activities at the dargah (Sufi lodge) located near Çakmaklı village along the Hadımköy road in Istanbul. He passed away there on January 30, 1997, and was buried in the garden of the dargah.
Throughout his life, Shaykh Muhammad Osman Siraceddin (K.S.) founded madrasas, disseminated Sufi education, guided communities across multiple regions, and cultivated a wide circle of followers. Around his khanqah, he established facilities for education, lodging, food distribution, and healthcare, ensuring that all functions were managed in an organized and communal manner.
