Detailed Explanation — Wisdom (394): Don't say what you don't know, but what you know, don't say everything. Because Allah (swt) has imposed certain duties on all your organs through which He will bring proof against you on the Day of Resurrection.

This wisdom from Imam Ali (a.s.) serves as a reminder of the profound impact our words can have. Historically, it was articulated during a time when social and political complexities were on the rise, necessitating a careful approach to communication. The influence of speech was significant, and there was a pressing need for individuals to use their words wisely.

One of the main themes in this wisdom is the importance of speaking within the bounds of our knowledge. Imam Ali (a.s.) teaches us that it is better to remain silent about what we do not know. This is a moral lesson emphasizing the need to avoid unnecessary or harmful speech.

The key phrase "many words have more impact than an attack" suggests that sometimes the power of words can surpass that of physical aggression. It serves as a reminder to be cautious in our choice of words, as they can profoundly affect others' lives.

On a spiritual level, this wisdom reminds us that on the Day of Judgment, Allah (swt) will question us about our actions and words. Therefore, we should exercise caution in our speech. This also serves as a practical takeaway that we should prioritize truth and knowledge in our conversations.
