According to the ulema and reliable sources of religious imitation, the majority of renowned ulema, jurists and experts of traditions have attended Imam Sadiq's classrooms and enjoyed his endless knowledge. Among his highly distinguished students we can name Abu Hanifa, Malik ibn Anas, Sofyan Thowri, Sofyan bin Ayeenah, Sha'abat ibn al-Hajjaj, Yahya bin Saeed Ansari, Yahya al-Qatan, Ayyoub al-Sajestani, Abu Amro ibn al-Ala, Abdulaziz al-Davardi, Suleyman bin Balal, Ibn Jaridj, Ibn Ishaq, Rouh ibn al-Qassim, Vahab ibn Khalid, and a large number of other ulema and traditionalists.
Once Abu Hanifa Na'man ibn Sabet was asked: "Who is the most learned jurisprudent you have ever met?"
He replied: "I have never met a religious jurisprudent more learned than Jafar bin Muhammad (meaning Imam Sadiq)."
