Note 271 — Chapter I
David Shea translation
The Imam Reza was the eighth Imam of the race of Alí; he was called Alí Ben Mússa al Kadhem, before he received the title Reza or Redha (one in whom God is pleased) from the Khalif Almamúm, when the latter appointed him his successor, but survived the Imam, who died A. D. 818.—A. T.
