4. Ali ibn Abi Talib (656-661): Ali's caliphate is portrayed as tumultuous, marked by civil strife, notably the First Fitna (civil war). The battles of Jamal and Siffin are critical events explored, along with the rise of the Kharijites.

5. Umayyad Caliphate (661-750): The narrative transitions to the Umayyads, detailing the transition of power to Muawiya I and the establishment of the hereditary caliphate. The Marwanid branch is discussed, focusing on their attempts to stabilize and expand the empire amid ongoing opposition.
