佛說目連問戒律中五百輕重事經 1.120

1.120

問：「沙彌犯十戒一二三不悔，受大戒得不？」答：「若憶而不悔，不得。都不憶、若不知法，受得。夫受戒法，師應問沙彌：『汝不犯戒不？』答若言犯，即教懺悔。若本師不問，壇上師應問。若都不問，師犯捨墮。」

Question: "If a śrāmaṇera violates one, two, or three of the ten precepts and does not repent, does he obtain the full precepts?"
Answer: "If he remembers and does not repent, he does not obtain them. If he does not remember at all, or does not know the Dharma, he obtains them. Now, in the procedure for receiving precepts, the master should ask the śrāmaṇera: 'Have you not violated the precepts?' If he answers that he has violated them, he should immediately instruct him to repent. If his original master does not ask, the master on the platform should ask. If neither asks at all, the masters commit a naiḥsargika-pāyattika."
