Traditions 35 to 43
Excellence of Knowledge and Eminence of Scholar

35. Imam Musa al-Kazim (p): While the Prophet Muhammad (p) was entering a mosque, he saw a person surrounded by a huge crowd.
Prophet Muhammad (p): Who is this person?
The Prophet (p) was told: This person is an ‘Allamah’ (a scholar).
The Prophet (p): Who is an Allamah?
The Prophet (p) was told: Allamah is a person who is most learned among all people about the lineage (family tree) of the Arabs and the historical events of the pre-Islamic era and an erudite Arabic poet.
The Prophet (p): Ignorance of this kind of knowledge will not discredit anyone and will not be profitable to anyone who possesses it. True knowledge is of three kinds:
a. Knowledge of the fundamental verses (of the Noble Quran, 3:7),
b. Knowledge of the requirements of equity and moderation, and
c. Knowledge of the Islamic code (as-Sunnah). The rest is additional excellence.(B2, C2, T1)

37. Imam Jafar as-Sadiq (p): When God wants to favour any of His servants; He bestows upon him the knowledge of religious jurisprudence.(B2, C2, T3)
38. Imam Muhammad al-Baqir (p): Excellence, nay super-excellence, lies in the knowledge of religious jurisprudence, patience in adversity and regulation of expenses.(B2, C2, T4)

39. Imam Jafar as-Sadiq (p): Learned men are the custodians (of religious knowledge), the pious ones are the fortresses (who safeguard against invasions) and the vicegerents (of the prophets) are the leaders (of the believers).
According to another tradition,
The Imam (p) said: The scholars are beacons of light, the pious are fortresses and the vicegerents are leaders.(B2, C2, T5)

40. Imam Jafar as-Sadiq (p) addressing Basheer, a believer: O Basheer, remember that those of our community who do not attain the knowledge of religious jurisprudence will not gain any merit. Because, the one who has no knowledge of religious jurisprudence will have to depend on others (in this field) and the one who depends on others will be led by them through the gates of ignorance and the members of our community will remain unaware of this misguidance.(B2, C2, T6)

41. Prophet Muhammad (p): There is no good in life except for two categories of people; the scholar who is obeyed and the listener who listens attentively.(B2, C2, T7)

42. Imam Muhammad al-Baqir (p): A learned person who avails himself of his knowledge is far better than seventy thousand worshippers of God.(B2, C2, T8)

43. Imam Jafar as-Sadiq (p) was asked to describe a person who had made it a habit to quote the traditions, exhortations and sayings of the Imams (p) to people and instill in their hearts and the hearts of the followers of the Imams (p) (the Shias), and other devoted worshippers of God who not follow this example.
The Imam (p): The narrator who makes an impact on the people is better than a thousand devotees.(B2, C2, T9)
