«يُمُوتِ الْمِعَلِّمْ وِهُوَّ يِتْعَلِّمْ»

Mastery is never complete. Here the 'teacher' (mi'allim) is the master of a trade, a skilled senior practitioner rather than a schoolteacher, and the idea extends to scholars too. However skilled or learned such a person becomes, learning ends only with life.

In Arabic, mi'allim rhymes with yit'allim, and both words share one root, setting the one who teaches against the act of learning. The saying teaches humility: seniority or reputation does not exempt anyone from correction, curiosity or study.

Use it to encourage humility in experts, to answer someone who claims there is nothing left to learn, or to praise an experienced person who still seeks new skills. It also works as gentle self-deprecation when a veteran admits a fresh discovery.
