Detailed Explanation — Wisdom (336): When the news of the martyrdom of Muhammad Ibn Abi Bakr (may Allah have mercy on him) reached him, he said, "We are as sad and worried about his death as the enemies are happy about it." Undoubtedly, they had one less enemy. And we lost a friend.

In Wisdom (336), Imam Ali (peace be upon him) highlights a profound truth that the one from whom something is requested remains free until they make a promise. This saying indicates that a person's freedom and autonomy are intertwined with their choices and commitments. When someone makes a promise, they limit their freedom in a specific direction.

This wisdom was articulated in the context of Imam Ali (peace be upon him) receiving the news of the martyrdom of Muhammad Ibn Abi Bakr. At this moment, Imam expressed that they were as saddened by his death as their enemies were joyful. This statement carries a depth of understanding regarding the value of friendship and the reality of enmity.

A key lesson here is the importance of keeping promises. Once a promise is made, an individual's responsibilities increase, and their freedom is affected. Therefore, we should take our commitments seriously to ensure fairness to ourselves and others.

This wisdom also teaches us to appreciate our friends and to mourn their losses. By mentioning the enemies' joy, Imam Ali (peace be upon him) illustrates the nature of friendship and enmity.

On a practical level, this wisdom urges us to recognize the significance of promises in our lives and to strive to fulfill our responsibilities. Doing so will not only enhance our character but also strengthen our social relationships.
