注維摩詰經 3.309

3.309

肇曰：如來無疾，言疾則謗。生曰：苟云是實，為謗佛也。以此言之，無乞乳理，故令還去焉。

[Seng]zhao says: “The Tathāgata has no illness; to say he has an illness is to slander him.” [Dao]sheng says: “If one says this is real, it is slandering the Buddha. Given this, there was no reason to beg for milk; hence he told him to turn back and leave.”
