四分律比丘含注戒本 2.367

2.367

不犯者：宿受食與父母；若塔、舍作人，計價與，後乞食比丘從作人邊乞得者。若鉢盂孔罅食入，如法洗之，餘不出者得。若宿受酥、油灌鼻，若隨唾出棄，餘者得。

Exceptions: giving food received overnight to one's parents; or calculating wages and giving it to workers on stūpas or monastic dwellings, and later an alms-begging bhikṣu begs and receives it from the workers. If food enters cracks or crevices in the bowl, and one washes it according to the rule, any remaining portion that does not come out is permissible. If ghee or oil received overnight is poured into the nose, if it is spat out and discarded with saliva, the remainder is permissible.
