俱舍論記 19.198

19.198

「反詰記者至無便求非」者，此釋第三反詰記者。若人諂心欲求過非，請言：願尊為我說法。應反詰彼：法有眾多，欲說何者？不應分別三世等法。若無所知者，乃至令彼默然而住。若有所知，令彼自記，無便求非。

On the passage from "An answer by counter-questioning" to "leaving no opportunity to seek fault": this explains the third, the answer by counter-questioning. If a person with a deceitful mind seeks to find fault, requesting: "May the Venerable One preach the Dharma for me," one should counter-question them: "Dharmas are manifold; which one do you wish to be spoken?" One should not analyze the dharmas of the three times and so forth. If they know nothing, one leads them to remain silent. If they have knowledge, one makes them answer for themselves, leaving no opportunity to seek fault.
