佛說目連問戒律中五百輕重事經 2.29

2.29

問：「主人請比丘十日供。十日食殘，用作五三日好食，犯何事？」答：「不犯。但不得更索，索犯捨墮。若不滿十日去，亦犯捨墮。」

Question: "A host invites bhikṣus for ten days of offerings. If food from the ten days is left over and used to make good food for three to five days, what offense is committed?"
Answer: "No offense is committed. However, they must not demand more; demanding more incurs a naiḥsargika-pāyattika offense. If they leave before completing the ten days, they also incur a naiḥsargika-pāyattika offense."
