Detailed Explanation — Wisdom (85): You are instructed in five such things. That if you make the camels go fast with their heels to get them, they will be able to do so. None of you should rely on anyone but Allah, and should not fear anything except his sin, and if any of you is asked about something that he does not know, then do not be ashamed to say, I do not know. There is a relationship between the head and the body. If there is no head, then the body is useless, and if there is no patience with faith, there is no virtue in faith.

In Wisdom (85), Imam Ali (peace be upon him) articulates a significant principle that guides an individual's intellectual and practical life. This wisdom emphasizes that one should never utter the phrase 'I do not know.' This phrase not only indicates a lack of knowledge but also affects a person's self-confidence and dignity.

Historically, this wisdom comes from a time when knowledge was highly valued, and the pursuit of knowledge was considered a great virtue. Imam Ali (a.s) consistently encouraged the quest for knowledge and stressed that one should not feel ashamed to acknowledge their ignorance.

The main themes of this wisdom include the pursuit of knowledge, self-confidence, and the importance of honesty. Imam Ali (a.s) clarified that those who hesitate to admit their lack of knowledge often face challenges in life. In contrast, those who acknowledge their weaknesses open themselves up to opportunities for learning and growth.

The moral and spiritual lessons here include the idea that the quest for knowledge should never cease. Individuals should always strive to learn and seek improvement while acknowledging their shortcomings. Additionally, this wisdom teaches us to place our trust in Allah and to fear our sins rather than being ashamed of our ignorance.
