Muhammad al-Baqir

Ja'far al-Sadiq (c. 699-765) taught in Medina for some thirty-four years. Descended from Ali and from Abu Bakr, he held to study over revolt, and the Twelver school of law carries his name.

Ali ibn al-Husayn (c. 658–712), called Zayn al-Abidin, was the only son of al-Husayn to survive Karbala. He lived in Medina as a transmitter of hadith and is remembered for his worship and secret charity.
