Yazaman or Yazman, surnamed al-Khadim ("the eunuch") (died 23 October 891) was governor of Tarsus for the Abbasids and chief military leader in the Muslim borderlands with the Byzantine Empire in Cilicia (the al-thughur al-Shamiya) from 882 to his death in 891.
[1][4] Yazaman led a major naval raid soon thereafter against the fortress of Euripos (Chalkis), comprising 30 large ships (of the type called koumbaria in Greek), but it was beaten off with great loss by the local governor of Hellas, Oineiates.
[1] The historian al-Tabari records that Yazaman also led a land raid in January/February 886 up to al-Maskanin (unidentified), and returned to Tarsus with no casualties but with much booty and captives.
[1] Yazaman's death was a keenly felt loss for the Muslims, who considered him one of their most valiant champions, alongside Umar al-Aqta and Ali al-Armani.
[11] According to the 10th-century account of al-Mas'udi (The Meadows of Gold, VIII, 74–75) a Greek convert to Islam reported to him that Yazaman was among the ten illustrious Muslims whose portraits were displayed in some Byzantine churches in recognition of their valour.
