四分律刪繁補闕行事鈔 3.140

3.140

三明內宿者。《五分》：使淨人於不淨地洗菜未竟，明相出者，則無犯。《四分》中，有比丘持食來，覓淨地未得，明相出，不犯。

Third is explaining storing overnight within. The Pañcavargika-vinaya states: If one has a kappiyakāraka wash vegetables on impure ground and has not finished when the appearance of dawn arises, there is no offense. In the Dharmaguptaka Vinaya, a bhikṣu brought food and was looking for pure ground but had not found it when the appearance of dawn arose; there was no offense.
