VI. The Sixth Imam, Ja'far, known as al-Sadiq (83/702-148/765)
The son of the fifth Imam, he lived in an increasingly favorable climate and was able to teach openly in Medina. Large numbers of scholars gathered around him to learn, including such famous Sunni figures as Abu Hanifah, the founder of one of the four Sunni schools of law. Towards the end of Imam Ja'far's life severe restrictions were placed upon his activities, as a result of growing Shi'ite unrest. More traditions are recorded from him than from all the other Imams together. He is so important for Twelve-Imam Shi'ite law that it is named the "Ja'fari School" after him. He is buried in the Baqi' cemetery in Medina.
