The completion of the religion on the day of Al-Ghadeer was the appointment of the Imam to succeed the Prophet (peace be upon him and his holy progeny) and represent him in propagating the Sharia and leading the nation. The Imams (peace be upon them) paid a lot of attention towards informing all the aspects of the religion especially the practical laws of the Sharia. The companions of the Imams propagated their teachings, and compiled the narrations (ahadeeth) in books. Although some of these books were destroyed, these traditions and narrations have survived and still act as a main source of Islamic research. Scholars have continuously strived to pass on these teachings from generation to generation for the sake of protecting the religion and its laws. As a result, the jurist can give their edicts in any practical issue, in such a way that the individual is not left unanswered.

As such, the Shia school of jurisprudence has developed as a result of the intellectual efforts of many great scholars throughout centuries, may Almighty Allah shower His blessings over their souls and guard those still amongst us, for their preservation of the religion from external influences and powers and maintained the religion in its pure and untainted form.</p>
