俱舍論疏 6.262

6.262

論「彼言事者至無因無果」，此述《婆沙》屬當無為名無事者，以無因故。若欲成立有部之宗，前經部難中一一應撿《正理》對經部也。

On the Śāstra's statement, "They say that 'fact'… without cause and without fruit": This sets forth that the Vibhāṣā assigns the unconditioned to be designated as "without fact" because it lacks cause. If one wishes to establish the Sarvāstivādin tenet, for each of the previous Sautrāntika objections one should consult the Nyāyānusāra to respond to the Sautrāntika.
