The life of Uthman ibn Affan—known as Dhun-Nurayn, the Man of Two Lights—is one of the most powerful and tragic stories in Islamic history. A companion beloved by the Prophet ﷺ, a man so modest that even the angels were said to feel shy in his presence, and the Caliph who united the Muslim world on a single Qur’an. But how did such a man end up besieged in his own home in Medina, cut off from water, and ultimately assassinated by rebels who claimed to be Muslims? In this documentary, OnePath Network explores the rise, leadership, and martyrdom of the third Caliph—uncovering the events that led to the first civil war in Islam and the moment many scholars say the unity of the Ummah was shattered.
