四分律刪繁補闕行事鈔 2.200

2.200

譏教尼人戒二十三。六緣：一是僧差，二情存為法，三內心嫉忌，四說為飲食，五言了，六前人聞知。不犯者：其事實爾；為供養故，教授、誦經、受經、若問；若戲、若錯，一切不犯。

Precept twenty-three: slandering one who instructs bhikṣuṇīs. There are six conditions: first, [the instructor] was designated by the saṃgha; second, [his] mind was fixed on the Dharma; third, one inwardly harbors jealousy; fourth, speaking [of him as doing it] for food and drink; fifth, completing the speech; sixth, the other person hears and understands it. As for non-offenses: the matter was truly so; [he did it] for the sake of offerings, instructing, reciting scriptures, receiving scriptures, or asking questions; or if spoken in jest, or mistakenly—in all such cases, there is no transgression.
