佛說目連問戒律中五百輕重事經 2.151

2.151

問：「五戒若不能持，得中還不？」答：「得還。若欲都還五戒者，合三自歸還，言：『從今日佛非我尊、我非佛弟子。』如是至三。法亦爾。若還一二三四者，但言：『我從今日不能復持某戒。』如是至三。若不滿三，戒猶成就。」

Question: "If one cannot uphold the five precepts, may one return them mid-way?" Answer: "They may be returned. If one wishes to return all of the five precepts, one returns them together with the Three Refuges, saying: 'From this day forward, the Buddha is not my Honored One, and I am not a disciple of the Buddha.' This is repeated up to three times. It is likewise for the Dharma. If one returns one, two, three, or four of them, one merely says: 'From this day forward, I can no longer uphold such-and-such precept.' This is repeated up to three times. If it falls short of three times, the precepts still remain intact."
