俱舍論記 9.172

9.172

「所說四句至所立三際」者，經部破望滿四句。經說已生皆通十二支，唯言過、現，豈不相違？或生老非在未來，汝說已生唯過、現故。若二非未來，便壞前三際。

Regarding "the four alternatives stated ... the three temporal limits established": the Sautrāntika refutes the four alternatives of Pūrṇa. The sūtra states that "what has dependently arisen" applies throughout the twelve members; to say it pertains only to the past and present, is this not contradictory? Or again, birth and old age would not be in the future, because you say that what has arisen pertains only to the past and present. If those two were not in the future, that would destroy the three temporal limits established earlier.
