I said to Abi Abdillah عليه السلام: I do sit in the Masjid – and the people come and ask me questions, so if I do not answer them they do not accept from me (i.e. they insist on answers), and I dislike answering them based on your verdicts and according to what has come from you (i.e. since they are not Shia), so he عليه السلام said to me: look at what you know is from their own verdicts and inform them about that (i.e. answer them using their own sources and scholars).
