Sermon (158) is an important discourse by Imam Ali (a.s.) in which he discusses the description of Allah, the concepts of fear and hope, and the lives of the Prophets. This sermon was delivered in a historical context where Muslims were facing various challenges. In it, Imam Ali emphasizes the greatness and power of Allah, making it clear that His pleasure and mercy are the ultimate security.

Imam Ali highlights Allah's attributes, stating that He judges with knowledge and forgives with forbearance. This teaches us to place our trust in Allah's mercy and to acknowledge His greatness. The Imam elaborates on the idea that offering praise to Allah in a manner that pleases Him is our responsibility.

A significant part of the sermon addresses the themes of fear and hope. Imam Ali asserts that if someone claims to hope in Allah, this should be reflected in their actions. If there is no sign of hope in one's deeds, then that claim is false. This teaches us that our actions should align with our hopes for Allah's mercy and forgiveness.

The Imam provides examples from the lives of the Prophets, such as Moses, David, and Jesus (peace be upon them), to illustrate that worldly possessions and comforts held no significance for them. Their lives serve as a reminder that seeking Allah's pleasure and success in the Hereafter is the ultimate goal.

Another crucial aspect of the sermon is Imam Ali's emphasis on the transient nature of worldly life. Instead of being drawn towards the adornments and pleasures of this world, we should turn our hearts towards Allah. This sermon teaches us to prioritize our love for Allah and our quest for His pleasure over the fleeting attractions of this world.
