Sharfuddin Ahmed Yahya Maneri, popularly known as Makhdoom-ul-Mulk Bihari[2] and Makhdoom-e-Jahan[3] (1263–1381), was a 13th-century Sufi mystic and saint active in medieval Bihar.

[7] His maternal grandfather Peer Jagjot, who is buried at Kachchi Dargah, near the Ganges in Patna district, was also a revered Sufi of the Suhrawardiyya order.

His elder brother Makhdoom Jaleeluddin Maneri (buried at Badi Dargah in Maner Sharif) accompanied him there and introduced him to his pir (spiritual guide) Sheikh Najeebuddin Firdausi.

[4] To shun material comforts, Sheikh Sharfuddin Ahmed bin Yahya Maneri went into the forest of Bihiya (about 15 miles west of Maner).

[11] His tomb lies at Badi Dargah (Bihar Sharif Nalanda), in a mosque to the east of a large tank, with masonry walls ghats, and pillared porticos.
