In Sermon (165), Imam Ali (peace be upon him) delivered significant guidance to Muslims at the onset of his caliphate. This sermon was given during a pivotal moment when Imam began his leadership, emphasizing the importance of Allah's Book and its guidance. He stated that Allah has sent down a Book that clarifies good and evil, urging Muslims to choose the path of goodness and avoid evil.

The Imam stressed the importance of fulfilling obligations, indicating that these duties should be performed for Allah, leading to Paradise. He also highlighted the dignity and sanctity of Muslims, stating that a true Muslim is one from whom other Muslims are safe from harm by tongue and hand. This ethical principle teaches us to respect each other's rights.

The Imam pointed to the reality of death, emphasizing that it is a universal truth relevant to everyone. He advised Muslims to remain light-hearted to catch up with those who have passed before them, reminding them to fear Allah in their dealings. This counsel serves as a reminder that life in this world is temporary, and we must prepare for the hereafter.

Additionally, the Imam underscored the importance of obeying Allah, stating that we will be questioned about everything, even about lands and livestock. This teaches us to reflect on our actions and live according to Allah's pleasure. The Imam concluded by advising that when we see goodness, we should seize it, and when we see evil, we should turn away from it. This guidance encourages us to choose the right path in all circumstances.
