In the book The Umayyad and Abbasid States, Sheikh Muhammad Al-Khudari presents his lectures on Islamic history, focusing on the Abbasid Caliphate in the East. The Abbasid history, a significant part of Muslim history, spans from year 132 to 656. The Abbasid family retained the caliphate title in Egypt until 923. Al-Khudari, in his lectures, does not follow them from Iraq to Egypt, but rather keeps their status there tied to Egyptian history.

He puts effort into depicting their political status from the inception of their caliphate through their advocates in Khurasan and Iraq to their end at the hands of Hulagu Khan, grandson of Genghis Khan. He explains this status throughout the different stages of the state from strength to weakness, clarifying the reasons that elevated this state to the peak of power and influence, and the causes that led to its decline.

He concludes by summarizing these causes, leaving the scientific history for special lectures that encompass the entire scientific history of Islam due to its interconnected nature.
