佛說目連問戒律中五百輕重事經 2.15

2.15

問：「鉢云何失？」答：「若緣缺、若穿穴、若裂、若油不捨、盡是失。緣缺、穿穴，不可復持。裂者，綴已施人，人還更受。油不捨亦爾。若棄，出界經宿不失。」

Question: "How is a pātra lost [as a valid bowl]?"
Answer: "If its rim is chipped, if it is perforated, if it is cracked, or if it has absorbed oil and has not been renounced—all these constitute loss. If the rim is chipped or if it is perforated, it can no longer be kept. If it is cracked, once stitched together it must be given to another person, and when that person returns it, it is formally received again. The same applies to one from which oil has not been renounced. If it is renounced, leaving the sīmā and spending the night apart does not constitute loss."
