The Islamic jurist Abd-al Mazeddin, better known in Maverannahr under the name of Khoja Abdu, was reputed to be an expert in Sharia and was one of the most respected qazis in Samarkand. He died about 861 and was buried according to Muslim custom in the garden of his vast estate, located in the southeastern part of Samarkand near the fortress wall of the outer city. Regarding the origin of Abd-al-Mazeddin, the sources differ. Abu-Tahir-Khoja in his book "Samaria" calls him the son of a certain Khoja Muhammad Yakub and the grandson of Khoja Abu ibn Usman. At the same time, the Islamic theologian Abu Hafsa Najmetdin Umar in his "Kandiya" traces his genealogy from Caliph Usman and, accordingly, to the Prophet Muhammad himself. Probably, talk about the relationship of Khoja Abdi with the prophet became the reason for the emergence of his cult.
