8-7 Ahmad ibn Ziyad ibn Ja’far al-Hamadani - may God be pleased with him - narrated that Ali ibn Ibrahim ibn Hashem quoted on the authority of his father, on the authority of Soleiman ibn Hafs al-Marwazi, “Harun Ar-Rashid arrested Musa ibn Ja’far (s) in the year 179 A.H. (794 A.D.). He (s) died in prison at Baghdad on the twenty-fourth or twenty-fifth day of the (Arabic) month of Rajab in the year 183 A.H. (798 A.D.) when he was 54 years old. He was buried in the cemetery of the Quraysh. He served as a Divine Leader for 35 years and a few months. His mother was an Umm Walad who was called Hamida. She was also the mother of his brothers Ishaq and Muhammad - the sons of Ja’far (s). Musa ibn Ja’far (s) clearly appointed his son Ali ibn Musa Al-Ridha (s) as the Divine Leader after him.
