The rituals of Hajj, one of the fundamental pillars of Islam, have always held a special place in the religious and social unity of Muslims. However, the performance of these rituals during the early Abbasid Caliphate (132-232 AH) faced serious threats and security crises such as banditry, armed rebellions, religious and political conflicts, as well as environmental crises including drought and outbreaks of contagious diseases, which jeopardized the safety of pilgrims and the stability of the Hijaz region. The primary objective of this study is to identify, analyze, and explain the various dimensions of these challenges and to examine their security impacts on the order and public safety of the Hajj rituals. To achieve this goal, a library-based methodology combined with a descriptive-analytical approach has been employed; accordingly, by collecting and reviewing credible sources, the events, causes, and consequences of the security threats to Hajj have been described, assessed, and analyzed. The results indicate that these crises and disturbances related to the Hajj rituals during this period not only endangered the physical and financial security of the pilgrims but also weakened the political cohesion of the Caliphate, leading to repeated interruptions in the performance of the rituals and increased costs related to travel and securing the Hajj.
