The maqam attributed to Luqman — after whom a sura of the Qur'an (Sūrat Luqmān) is named and who is described as having been 'granted wisdom' — is among the tombs adjoining the eastern section of the Tarsus Grand Mosque (Ulu Camii / Câmi-i Nûr). Islamic tradition debates whether he was a prophet or a wise, righteous man; popularly he is regarded as the patron of physicians. The tomb sits alongside the maqams of Seth (Şît) and Caliph al-Ma'mun on the east of the Grand Mosque. Whether the grave truly belongs to Luqman is uncertain, so it is of maqam status.
