He became the Imam after his father, Imam Musa al-Kadhim, and was recognized for his wisdom and piety. Imam al-Ridha was appointed as the court scholar by the Abbasid Caliph al-Ma'mun, which allowed him to engage in discussions on various subjects, including religious and political matters. He passed away in 818 CE in Mashhad, where his shrine remains a significant pilgrimage site for millions of Muslims today.
