俱舍論記 6.96

6.96

「有謂未來至未來無故」者，答。有，謂前所定得未來苦法忍品，於後過、現已生苦法智品，以果必無在因前故，或同類因未來無故。

"Regarding 'There are [some], namely the future... because it does not exist in the future':" this is the answer. There are [some], namely the category of future dharma-forbearance of suffering definitively acquired previously, with respect to the category of dharma-knowledge of suffering already arisen later in the past or present; because a fruit definitively cannot precede its cause, or because a sabhāga-hetu does not exist in the future.
