Investigating the Discourses of the Ibn Bābwaih Area on the Thought of Ghaybah, relying on the book of Kamāl al-din wa tamām al-ni'mah.

Ibn Bābwaih's period of life is one of the most arduous periods in the history of Shiite Imami. Imam's ghaybah from the direct access of people in this period, along with the adverse activity of other sects, not only confronts the general public with comprehensive mystification, but also afflicts the scholars with various intellectual issues. In such a situation, Ibn Bābwaih, one of the greatest scholars of the Imami, began to write the book of Kamāl al-din wa tamām al-ni'mah. In this book, he attempted to scrutinize the most important discourse challenges of that period, which created the perplexity and ambiguity surrounding the Mahdi's Doctrine. Since these challenges are not explicitly mentioned in the book, this study attempts to understand this case by analyzing the data of Kamāl al-din wa tamām al-ni'ma’s book. The result of this study shows that Ibn Bābwaih has tried to discuss three issues:1) Proof of Divine Hujah as the son of Imam al-Askari; 2) Imam's absence and non-conflict with Imam's duties; 3) The longevity of Imam.
