In Sermon (100), Imam Ali (peace be upon him) discusses the Day of Judgment when Allah will gather all individuals for the reckoning of their deeds. This sermon was delivered in a significant historical context, where Imam Ali (a.s.) highlighted the seditions of his time and their consequences. It serves as a warning for those living in times of turmoil to understand the impacts of such events.

Imam Ali (a.s.) describes how on that day, people will stand before Allah in a state of humility, with sweat on their faces and the earth trembling beneath them. This imagery reflects the severity and fear of the Day of Judgment. A key message here is that worldly life is temporary, while the hereafter is eternal; thus, individuals should be concerned about their actions.

In this sermon, Imam (a.s.) also illustrates the forthcoming seditions, likening them to pieces of a dark night. These trials will be so intense that people will be unprepared to face them. This implies that during times of turmoil, individuals must exhibit patience and resilience, relying on Allah's assistance.

Particularly, Imam Ali (a.s.) laments the condition of Basra, indicating that certain places will inevitably face Allah's punishment, with inhabitants suffering immensely. This serves as a reminder that individuals must rectify their actions and remain steadfast in the path of Allah.
