Usāmah ibn Zayd

Usāmah ibn Zayd was the son of Zayd ibn Haritha, Muhammad's adopted son, and Umm Ayman, an Abyssinian servant of Muhammad. Born before the Hijrah, he belonged to the Kalb tribe through his father and was raised in close proximity to the Prophet. Muhammad appointed him commander of an expeditionary force to avenge the Battle of Mu'tah, where his father was killed. Despite initial objections due to his youth, Usāmah led a successful campaign into Byzantine Syria, paving the way for later Muslim conquests. He fought alongside Muhammad in the Battle of Hunayn and was noted for his loyalty and bravery. After Muhammad's death, Usāmah settled in Medina and died around 680 CE during the caliphate of Mu'awiyah.
