Knowledge is most beneficial when it is learned accurately, practiced and transmitted with sincere concern. Collecting facts merely to appear superior is not the purpose of teaching.
Practical teaching principles
1. Understand a matter properly before explaining it.
2. Use examples appropriate to the learner's level.
3. Avoid presenting unsupported claims as definite rulings.
4. Do not humiliate someone for asking.
5. Help the learner apply what has been understood.
يَتَعَلَّمُونَ means “they learn”; يُعَلِّمُونَ means “they teach.” The related forms distinguish receiving knowledge from conveying it to others.
