Background. Each theory in semantics and the method of understanding meaning is essentially based on semantic realities. It is for explication of these realities that various theories have been proposed as to the essence of meaning. Due to the importance of the problem of meaning for scholars of principles of Islamic jurisprudence, they have discussed the essence of meaning with specific care. The current article seeks to analyze some of the significant views of Muslim jurists concerning the theory of meaning. The method of this study is based on philosophical and linguistic description and analysis. The findings of this research show that Muslim jurists have studied the problem of meaning in various social, linguistic, philosophical, psychological and applied areas. Thus they have offered ideal, essential, conceptual and noumenal theories of meaning. But the present study via an extensive analysis of noumenal realities including true and mentally posited, external and mental, necessary and contingent existence and even impossible nothingness and possible nothingness, and the material and essential realities, philosophical secondary intelligibles, (existential relations), logical secondary intelligibles (mental realities), moral and legal, relative, nominal and linguistic realities as well as aspects of human understanding (existence, reference, referred) of noumenal realities has proven that meaning is an aspect of the "referred" of understanding of realities and the "essence of noumenal realities".
