The Holy Imam's main task was to safeguard the Message of Islam, to defend its originality, to call people towards it and to convey its principles and values.
During the reign of Imam al-Askari (A.S.), the school of Ahlul-Bayt (A.S..) was filled with knowledge, calling to Islam and defending it and spreading its ideas, the chief element of this act was done through the academic way.
Indeed, the Holy Imam (A.S.) had students, companions and narrators, some of whom had continued their task since the reign of his father and grandfather, while others joined in during the period of his divine leadership. All these students and narrators had studied under the Holy Imam (A.S.) and quoted him in narrating Islamic sciences and culture.
Sheikh Tusi mentioned the names of the narrators of Imam al-Askari (A.S.). Their number was about 99 narrators on different levels of knowledge and culture.
Indeed, the religious scholars who either narrated from Imam al-Askari (A.S.), or who studied under his school, or who were educated in the school of the Holy Imam (A.S.) and his forefathers, participated in developing the scholarly offering in the fields of jurisprudence, interpretation, narration, faith, literature, geography, and other sciences.
All these evidences indicated the greatness of this school and also refer to the scholarly status of the Holy Imam (A.S.) and his high rank among people.
