Eyyubizade Mustafa, known as Mustafa al-Mostari in the Ottoman scholarly world and gaining fame as Sheikh Yuyo (Šejh Jujo) in his hometown of Bosnia and Herzegovina, was a scholar and intellectual who lived in the 17th century. Having received his initial education in his hometown, he later went to Istanbul and studied for four years at the Sahn-i Seman Madrasa, where he be-came a scholar. After completing his education, he stayed in Istanbul for about fifteen years, teaching in several madrasas and publishing around sixty books alongside his scholarly activities. Upon the death of the mufti of Mostar in 1104 (1692), he returned to his hometown as the new mufti and continued his scho-larly activities there until the end of his life. In addition to his role as the mufti of Mostar, he taught at the Karagoz Bey Madrasa and other madrasas. He produ-ced works in various fields, including philosophy, theology, language, literatu-re, Islamic jurisprudence, and its methodology. Due to Sheikh Yuyo’s significant contributions to education, Mostar became a renowned cultural and educational center in the Herzegovina region, nurturing many scholars. After his demise on 15 Rabi’ al-Awwal 1119 ( July 16, 1707), he was buried in the Muslim Cemetery in Mostar. Since his death, his grave has become a revered pilgrimage site whe-re people pray and make supplications. The tomb, constructed in a rectangular plan and covered with a metal-caged, dome-shaped roof, is a variation of the typical baldachin structure. It was built around 1247 (1831) by Rıdvanbeyzâde Ali Pasha (Ali Pasha Rıdvanbegovic), 124 years after Sheikh Yuyo’s passing. The tomb, which was damaged during the Bosnian War (1992-95), has been restored and has reached the present day in good condition, reflecting the characteristics of the period in which it was originally built.
