Hussam al-Din al-Jarrahi (Arabic: حسام الدين الجراحي; died 1202 CE)[1][2] was an emir and the personal physician of Saladin, who founded the Ayyubid dynasty and rose to become a prominent Muslim leader during the Crusades.
Due to his extensive work in medicine, Hussam received the title of jarrah (جراح), meaning "surgeon" in the Arabic language.
[3][4] Although his exact date of birth is unknown, Hussam was primarily active during the 12th century; he established a Sufi-focused zawiya known as the Zawiya Jarrahiyya in Jerusalem.
[5] Hussam was buried on the grounds of the school, which is today located in the East Jerusalem neighbourhood of Sheikh Jarrah, for which he serves as the namesake.
[6] In 1202, a tomb was built on his burial site and subsequently became a destination for Muslim mystics and visitors.
