55-1 (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 Abul Khayr Salih ibn Abi Hammad, on the authority of Al-Hassan ibn Ali al-Washsha’, “I had written down many questions and I used to have them with me all the time. Before becoming certain about the Divine Leadership of Abil Hassan Ar-Ridha’ , I had compiled those questions in the form of a book that contained narrations from his forefathers, etc. I wanted to test him concerning his Divine Leadership. I picked up that book, hid it in my sleeves, and went to his house. I wanted to hand him the book when I was alone with him and ask him what he thoughtabout it in order to find out about the degree of his scientific mastery. Therefore I sat in a corner of the house thinking about seeking permission. There were some people sitting near the door of Ar-Ridha’’s room talking with each other. Then as I was thinking about asking for permission to see him , one of the servants came out with a book in his hand and loudly announced, ‘Who is Al-Hassan ibn Ali al-Washsha’ - the son of the daughter of Elias from Baghdad?’ I stood up and said, ‘That’s me. What do you want?’ The servant said, ‘I have been told to hand you this book. Take it.’ I took the book, went out and sat in a corner to read it. I swear by God that he had posed all the questions which I had recorded in my book to ask him, and had answered all of them. Then I became certain that he was the Divine Leader and stopped being one of the Waqafites.”
