Şeyh Mansur Simati (also called Şeyh Mehmet Simati) is, by tradition, a Companion of the Prophet who set and managed the Prophet's table, hence the epithet 'Simati' (from 'simat', meaning table/feast). He is reported to have come to the region during the caliphate of Abu Bakr, opening a table for the poor and needy, and was martyred in Kilis. His tomb stands about 3 km south of Kilis amid vineyards and gardens — a white-stone structure with a pointed (conical) dome, roughly 7.30 x 7.30 m, bearing Seljuk and Ottoman traces. Alongside Şeyh Mansur, the tomb also holds a small domed section attributed to Şeyh İzzeddin and Şeyh Yusuf. The account derives largely from Evliya Çelebi's Seyahatname.
