四分律比丘含注戒本 2.279

2.279

尼同犯。不犯者：宿受；病，過受食；若居士請住，「我為沙門釋子故設此食」；若檀越次第請食；若兒、女、妹、婦次第請；或今日受此人食，明日受彼人食；若道斷等難者。

(Bhikṣuṇīs share the offence. As for non-offences: receiving for an overnight stay; being ill and receiving meals in excess; if the householder invites him to stay, saying, 'I have prepared this food for the sake of the śramaṇas, the sons of the Śākya'; if donors invite him to meals in turn; if sons, daughters, sisters, or wives invite him in turn; or receiving this person's food today and that person's food tomorrow; or if there are perils such as the road being cut off.)
