Badr al-Hammami Badr al-Hammami Badr ibn ʿAbdallāh al-Ḥammāmī, also known as Badr al-Kabīr ("Badr the Elder"), was a general who served the Tulunids and later the Abbasids. Of Greek origin, Badr was originally a slave of the founder of the Tulunid regime, Ahmad ibn Tulun, who later set him free. In September 893, along with Muhammad ibn Abba, and the governor of Tarsus, Ahmad ibn Tughan al-Ujayfi, Badr led an expedition against the Byzantine Empire, reaching as far as al-Balaqsun (unidentified, possibly Carian or Lycian Telmessos).

Battle of al-Qādisiyyah and led a group of Mubarizuns, from his Syrian contingent who were also the veterans of Battle of Yarmouk, through the Sassanids' right center towards Rostam's headquarter. Rostam again personally led a counterattack against the Muslims, but no breakthrough could be achieved. At dusk, the two armies pulled back to their camps. On 18 November, Rostam wanted a quick victory, before more Muslim reinforcements could arrive. The Elephant corps was once again in the front of the Sassanid army, giving him the advantage. Pressing this advantage, Rostam ordered a general attack along the Muslim front, using his full force. All
