Ja'far ibn Muḥammad al-Ṣādiq (; 700 or 702–765 C.E.), commonly known as Ja'far al-Sadiq or simply al-Sadiq (The Truthful), is the sixth Shia Imam. He was a descendant of Ali from his father Muhammad al-Baqir's side and a descendant of Abu Bakr from his mother Farwa's side. He is the last individual to be recognized by all Shia sects as an Imam (except the Zaydiyyah), and is revered by Sunni Muslims as a transmitter of Hadith and a prominent jurist.
