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.
