Scientific School of Imam Al-Baqir(a.s) 4

Ibn Kathir writes: I have never seen the scholars of Islam in any assembly like as assembly of Muhammad ibn Ali (a.s) , they insignificant scientifically. I saw al-hakam Ibn Utaybah, who was famous in Fiqh, who in the service of Muhammad Baqir(a.s), like a child in front of the master, fell on his knees, became fascinated by his words and personality.
