47-40 (The author of the book narrated) my father - may God be pleased with him - narrated that Sa’d ibn Abdullah quoted on the authority of Muhammad ibn Isa ibn Obayd, on the authority of Abi Ali Al-Hassan ibn Rashid, “I had received several loads of goods. The messenger of Ar-Ridha’ came to me before I could open them and see what they were. He told me that Ar-Ridha’ says, ‘Send me a notebook since I do nothave any at home.’ I asked myself, ‘Should I look around for what I do not know of just because I have acknowledged him (as the Divine Leader)?’ I looked around but could not find anything. As the messenger wanted to return, I called out to him and said, ‘Wait a little.’ I opened some of the bags of the newly-arrived loads and found a notebook in them of which I was unaware of. I knew that the Ar-Ridha’ would not send for something without a reason, and I sent it for the Imam .”
