佛說目連問戒律中五百輕重事經 2.30

2.30

問：「主人請供十日食，自裁作一月食，得不？」答：「打揵槌得。若不打揵槌，僧有出去者、若不施後人食，後人食己分盡，食他分一飽犯棄，不飽犯捨墮。」

Question: "A host invites bhikṣus to offer ten days of food, but they portion it themselves to make one month's food. Is this permissible?"
Answer: "If they strike the ghaṇṭā, it is permissible. If they do not strike the ghaṇṭā, and there are bhikṣus who depart, or if they do not give food to those who arrive later: when those who arrive later exhaust their own shares, if they eat a full meal from another's share, they commit a pārājika offense; if not a full meal, they commit a naiḥsargika-pāyattika offense."
