Muhammad's revelations in the caves of Mecca and the death of Ali roughly forty years later frame this five-part series from Caspian Report on Islam's founding century. It opens with the Prophet's early followers and moves through the Rashidun Caliphate: Abu Bakr, the first non-relative to accept Islam, who held the caliphate for two and a half years, and his military commander Umar, whose campaigns took Mesopotamia, Persia, Syria, and Egypt in roughly thirty years. Uthman extends that expansion before rebels assassinate him, and Ali's contested succession opens the rift between Sunni and Shiite Muslims that runs through the rest of the series. The narration compares the arc, from revelation to Ali's death, to the Passion narrative in Christianity, and notes the odd resemblance the early Caliphate bears to a democracy, with each leader chosen by council rather than inheritance. Presentation is plain, static maps and images over narration, but the account stays grounded in specific campaigns, names, and successions rather than generalities.
