Muhammad ibn ‘Alī ibn Mūsā (Arabic: محمد ابن علی ابن موسی ) (circa April 12, 811 - c. November 29, 835) was a descendant of the Prophet Muhammad. He was also called Abu Ja'far, Ibn al-Ridha ("the son of al-Ridha); al-Jawād ("the generous"), and al-Taqī ("the pious"). In the largest branch of Shia Islam, the Twelver or Athnā‘ashariyyah branch, Al-Jawād holds a sacred place as the ninth of the Twelve Imams. According to Shiite accounts, he was poisoned by his wife and died at age 25, the shortest-lived of the Twelve Imams.
