In Sermon (17), Imam Ali (a.s.) condemns those who sit on the judge's seat without being qualified. This sermon reflects the state of society at a time when some individuals attempt to make important decisions without the necessary knowledge and insight. The Imam states that the most hated people to Allah are of two types: the first is one who has strayed from guidance due to his own sins, and the second is one who claims knowledge while being ignorant.

The Imam describes the characteristics of those who make judgments based on their ignorance. They consider themselves scholars, yet their knowledge is superficial. Such individuals believe their opinions are correct and act upon them, despite the many errors they contain. The Imam clarifies that these people mislead others due to their ignorance, and their unjust rulings result in the shedding of innocent blood.

This sermon also highlights the importance of knowledge. The Imam emphasizes that the proper use of knowledge is essential, and anyone who does not understand the essence of knowledge is unworthy of the position they hold. This teaches us that we should always seek knowledge and obtain our information from credible sources.

Furthermore, Imam Ali (a.s.) mentions the significance of the Qur'an, stating that its verses must be presented correctly. When the Qur'an is misapplied, it becomes worthless to people. Conversely, when recited properly, it becomes the most valuable thing. This sermon serves as a reminder that we need knowledge, insight, and a proper understanding of the Qur'an to make sound decisions.
