If a student asks a straightforward rule and the teacher knows it, explaining it accurately is a trust. Yet a teacher must not invent an answer to a question beyond their expertise. The word عَلِمَهُ matters: the knowledge must actually be possessed.
Example 1: Explain a known religious or language rule without arrogance or envy.
Example 2: In an uncertain matter, say “I need to verify this” and consult qualified scholarship.
Example 3: Do not disclose someone’s private information under the pretext of “spreading knowledge.”
The responsibility is to share reliable guidance, not guesses, rumors, or unrelated confidences.
