Sciences Disseminated by Imam Sajjad (Zayn al-Abidin)

As for the sciences of Ima`m Zayn al-'Abidin, peace be on him, they were an automatic extension to the sciences of his fathers, who inherited them from the Prophet, may Allah bless him and his family. The historians unanimously agreed that the Ima`m was the most knowledgeable of the people in all sciences and arts. The proof of this is that the religious scholars and reporters narrated countless sciences on his authority.( Khulasat Tahdhib al-Kamal, p. 23)
