In spite of the efforts made in the Arabic language on the syntactic and semantic level, it remains very restricted, even those on the Arabic Sacred Book are few and very limited, due to its difficulties and peculiarities. In this paper we tried to shed the light on some of the recent works that have been conducted to present a semantic representation and manipulation of the Islamic texts to define the problems, limitations and the possible future works that need our intention to improve the semantic support in the Arabic religious texts. Furthermore, we intent to briefly present our project that aims to help us reading, understanding, and interpreting the Islamic legislative sources. The goal of this project is divided into two main tasks which are the creation of an ontology representing the Islamic knowledge and the development of a system which can analyze this knowledge. The ultimate goal is to assist the muftis and facilitate their job.
