俱舍論記 12.104

12.104

「引不極成為能立故」者，論主出非理。凡所引喻，彼此極成。汝引不極成為能立喻故。

"Because you adduce what is unestablished as a proof": The author of the treatise points out what is unreasonable: Whatever example is adduced must be mutually established by both parties. You adduce what is unestablished as an establishing example.
