H 18 - It is narrated from Ahmad bin Mehran from Muhammad bin Ali from Zahak bin Ashath from Dawood bin Zarbi that he said: I brought some money to Abu Ibrahim [Imam Musa Kadhim ]. He took some of it and left some of it. “May God set you right,” I said, “Why have you left it with me?” “The one who will be in charge of the authority will ask you for it,” he told. When the news of his death came, Abul Hasan, Ridha summoned me and asked me for that money and I paid it to him.
