I was standing with my father. Abu Salt al-Harawi, Ishaq ibn Rahawayh and Ahmad ibn Muhammad ibn Hanbal were also present there. My father said, “Each of you should narrate a tradition for me.” Abu Salt al-Harawi said, “Ali ibn Musa Al-Ridha (s), who I swear by God was really pleasant as his name indicates, quoted on the authority of his father Musa ibn Ja’far (s), on the authority of his father Ja’far ibn Muhammad (s), on the authority of his father Muhammad ibn Ali (s), on the authority of Ali ibn Al-Hussein (s), on the authority of his father Al-Hussein ibn Ali (s), on the authority of his father Ali ibn Abi Talib (s) that God’s Prophet (s) said, “Faith consists of talking and action.” When we left Ahmad ibn Muhammad ibn Hanbal said, “What form of chain of traditions was that?” My father said, “It is the healing medication for the insane. If they treat a mad man using it, he will be healed.”
