4-22 In another tradition it is narrated that (The author of the book narrated) my father - may God be pleased with him - narrated that Sa’d ibn Abdullah quoted Muhammad ibn Isa ibn Obayd, on the authority of Yunus ibn Abdir-Rahman, on the authority of Ja’far ibn Khalaf that he had heard Abul Hassan Musa ibn Ja’far (s) say, “One who can see his son that he will leave behind as a memory before he dies is prosperous. God has shown me the son that I will leave behind by giving him to me.” Abul Hassan Musa ibn Ja’far (s) was pointing at him - that is Al-Ridha (s).
