Today, identity in Social Sciences is very important and it is studied from different dimensions. One of its dimensions is the religious identity of which jurisprudence is the law of its behaviors. Regarding the role of jurisprudence in Shiite's identity, we face three perspectives: Some scholars, by ignoring the jurisprudential aspect, have tried to highlight the mystical aspect of Shiite and in some way associate Shiite's identity with Sufism. Others, like Ibn Taymiyyah, despite accepting the role of Shiite's jurisprudence in shaping Shiite's identity, but denied its legitimacy and the foundation of the Shiite is introduced by paganism and discord, and constructed by a Jewish person. The chosen theory in this article, which is the usual viewpoint of Shiite and some Western scholars have more or less acknowledged it, it is: since the beginning of formation of Shiite, religious judgments and how to interpret it and qualified authorities have played a key role in Shiite's identity. Some evidence of the truth of this claim is: the prevarication narrative, narratives that have revealed jurisprudential deviations and innovations after the age of the Prophet of Allah and some historical reports.
