In Sermon (19), Imam Ali (a.s.) addresses the treachery and hypocrisy of al-Ash‘ath ibn Qays. This sermon was delivered from the pulpit of Kufa at a time when divisions were growing among Muslims, and some individuals were attempting to undermine Islamic principles for personal gain. When al-Ash‘ath objected to the Imam's words, the Imam responded sternly, highlighting his hypocrisy and past allegiances to disbelief.

Imam Ali (a.s.) pointed out that al-Ash‘ath had been captured twice—once by unbelievers and once by Muslims—indicating his lack of loyalty to either side. His wealth and lineage did not save him from disgrace, which reflects the duality of his character, claiming to be a Muslim while conspiring against his own people. The Imam emphasized that one who raises a sword against their own community deserves to be loathed by both close and distant relations.

This sermon teaches us that the foundation of faith must be based on truth and loyalty. If a person betrays their community for personal interests, they lose their standing and trust. Furthermore, the consequences of hypocrisy and treachery are severe, leading to divine wrath and condemnation from both God and the community.

Imam Ali's (a.s.) sermon serves as a crucial lesson that we must remain faithful to our beliefs and principles and never betray our people. It also reminds us that a leader's primary duty is to protect their community and shield them from all forms of danger.
