Mu'in ad-Din had three daughters, who married Nur ad-Din, Mujir ad-Din, and a soldier named Margar respectively. In addition to Ibn al-Qalanisi's favourable depiction of him, the Christian chronicler William of Tyre also speaks very highly of Mu'in ad-Din: he showed "sincere fidelity" in his negotiations with the Kingdom of Jerusalem, and was "a man of much wisdom and a lover of our people." William of Tyre rendered his names in Latin as "Meheneddin" for Mu'in ad-Din and "Anardus" for Unur.
