金剛般若波羅蜜經註解 1.150

1.150

如來又慮善現未達般若性空，謂有言說，故又誥云：「如來有所說法不？」而善現了知說即無說，乃答云：「如來無所說也。」

The Tathāgata, moreover, was concerned that Subhūti had not yet realized that prajñā is empty in nature and would think that there is spoken discourse; therefore he asked again: "Has the Tathāgata expounded any dharma?" But Subhūti completely understood that expounding is non-expounding, and thus answered: "The Tathāgata has expounded nothing."
