Detailed Explanation — Wisdom (493): The worst brother is the one to suffer for. Sayyid Razi says that this is because it causes more pain, sorrow and hardship than what is possible, and the brother for whom hardship is done, will inevitably suffer from it. So he became the bad brother.

The worst brother is the one to suffer for. This wisdom reflects the depth and insight of Imam Ali (peace be upon him). Historically, Imam Ali (a.s.) faced various challenges during his time, including social injustice and a lack of brotherhood. In this wisdom, Imam Ali (a.s.) teaches us that a true brother is one for whom no hardship is necessary.

Key themes in this wisdom include the nature of human relationships and the moral behaviors that should underpin them. Imam Ali (a.s.) indicates that if one has to endure hardship for a brother, it suggests that this brother is not truly a brother in spirit. It is a harsh reality that sometimes people become burdens to one another, which negatively impacts love and camaraderie.

Key phrases such as "hardship" and "worst brother" highlight the necessity of love and respect in human relationships. If these elements are lacking, the bond becomes strained and burdensome. A fundamental moral lesson from this wisdom is that we should strive to improve our relationships so that we can be sources of ease and joy for one another.

Practically, this wisdom suggests that we should create ease in our relationships. We must treat our brothers and friends in a way that they do not feel burdened by our presence. In doing so, we can build a strong and loving community.
