Usama ibn Zayd

Usama ibn Zayd was born before the Hijrah to Zayd ibn Haritha, Muhammad's adopted son, and Barakah (Umm Ayman), an Abyssinian servant of Muhammad. He belonged to the Kalb tribe through his father and was raised in a family closely connected to the Prophet. Usama fought alongside Muhammad in battles such as Hunayn and was appointed by Muhammad to lead an expedition against Byzantine forces to avenge his father's death at the Battle of Mu'tah. Despite initial opposition due to his youth, Usama's leadership was affirmed by Abu Bakr after Muhammad's death, and his campaign successfully invaded Byzantine territory, paving the way for later Muslim conquests. He later settled in Medina and died around 680 CE during the caliphate of Mu'awiyah.
