1-94 (The compiler of the book narrated) that his father - may God be pleased with him - narrated that Muhammad ibn Yahya al-Attar quoted on the authority of Ayoob ibn Nooh, on the authority of Muhammad ibn Sin’an, on the authority of Musa ibn Bakr al-Vaseti, “I asked Abil Hassan Musa ibn Ja’far al-Kadhim (MGB) if he (MGB) saw anything wrong if someone says ‘may my father or mother be your ransom’ to his son or daughter? The Imam (MGB) replied, ‘It is being ungrateful to his parents if they are alive, but it is fine if they have passed away. My father Ja’far (MGB) used to say that whoever lives to see his successor is prosperous. In fact, I swear by God that He has shown me the successor after me.’”
