The word Imam al-Mubin occurred twice in the Koran
(36:12 and 15:79). The word Imam (pl. a'imma) means a model, an
exemplar, a teacher, a guide or a path. The word mubin means manifest,
apparent, present, or visible. Besides, the word mubin has a special significance. In Arabic, mubin and the root b-y-n means readily apparent. Thus, Imam al-Mubin means manifest or apparent Imam.
