Al-Mus'haf corpus is a new Quranic corpus rich in morphosyntactical information. To build such a corpus of the Quran, we used a semi-automatic technique which consists in using the morphosyntactic of Standard Arabic words "AlKhalil Morpho Sys" version 2 followed by a manual treatment in colaboration with experts in Arabic grammar. The corpus and the results we achieved can be used by researchers as baselines to test and evaluate their Arabic tools. In addition, this corpus can be used to train, optimize and evaluate existing approaches. Furthermore, the current corpus is always subject to further improvement.
