俱舍論疏 30.57

30.57

論「若見非見至非一切智」，又難。見、不見俱不可說，即應漸言。不可說佛是一切智、非一切智，即違經說佛是一切智故。

On the Śāstra's: "If both seeing and non-seeing [are inexpressible] ... not omniscient": Another objection. If both seeing and non-seeing are inexpressible, then one would gradually have to say that it is inexpressible whether the Buddha is omniscient or not omniscient, which would contradict the sūtra stating that the Buddha is omniscient.
