Usama ibn Zayd

It is very interesting in Islamic history that the Usama (R) had sent by the prophet in his last time as a leader of a troop of Islam to one of it's enemies. And the prophet had also appointed one as his subordinator namely Umar Bin Khattab (R). This teach us that leadership is a capability and the Usama was a powerful, capable leader.

Usama ibn Zayd ibn Haritha al-Kalbi (Arabic: أسامة بن زيد بن حارثة الكلبي, romanized: ʾUsāma ibn Zayd ibn Ḥāritha al-Kalbī) was an early Muslim and companion of the Islamic prophet Muhammad.

He was the son of Zayd ibn Haritha, Muhammad's adopted son, and Umm Ayman (Barakah), a servant of Muhammad.^[2]

Muhammad appointed Usama ibn Zayd as the commander of an expeditionary force which was to invade the region of Balqa in the Byzantine Empire to avenge the Muslim defeat at the Battle of Mu'tah, in which Usama's father and Muhammad's adopted son, Zayd ibn Harithah, had been killed.^[3] This campaign was known as the Expedition of Usama bin Zayd. Usama's campaign was successful and his army was the first Muslim force to successfully invade and raid Byzantine territory, thus paving the way for the subsequent Muslim conquest of the Levant and Muslim conquest of Egypt.
