One way to be aware of the common moral schools during the life of the Ahl al-Bayt (AS) is to know the thoughts of their students. It seems that the students of Ahl al-Bayt (AS) have played an important role in the formation and evolution of moral ideas of their time. One of the most important and influential Shiite figures in this period is Jabir bin Yazid Ja'fi. Among the students of Imam Baqir (AS), he is one of the special students of that Imam, and from the point of view of the general Muslim scholars, he is also considered a follower. Finally, understanding his moral thought must be considered important. The studies that have been done so far on Jabir's moral narratives reveal the ontological and anthropological foundations of his moral thinking; What are the people on the basis of which one can receive the supreme good that, in Jabir's view, should be achieved through moral conduct? However, they do not explain the meaning of the method of morally optimal conduct to achieve that supreme good. In this study, by analyzing the narrations received from Jaber Jafi, we are to recognize the method of optimal moral behavior from his point of view.
