四分律比丘含注戒本 2.597

2.597

其受戒人知年不滿，和尚及僧亦知，然眾中問「汝年滿不」，報言或滿或不滿，若疑，若不知，或默然，或僧不問。是中四種：若知，若疑，和尚波逸提，眾僧突吉羅；若謂、不知，俱不犯。若受三羯磨竟，和尚犯墮。若中間，若白未竟，若為作方便，若剃髮，若集僧，和尚一切吉羅，眾僧亦爾。比丘尼波逸提。不犯者，先不知，信受人語，若傍人證，若信父母語。若受戒已，疑者，佛言：「當數胎中年月，數閏月，若數一切十四日說戒以為年數，滿者開。」

(That person receiving ordination knows his age is not full, and the upādhyāya and the saṃgha also know; yet when asked in the assembly, "Is your age full or not?" he answers either that it is full, or that it is not full, or in doubt, or not knowing, or remains silent, or the saṃgha does not ask. Among these there are four kinds: if [the upādhyāya] knows or doubts, for the upādhyāya it is a prāyaścittika, and for the assembled saṃgha a duṣkṛta; if he assumes [the age is full] or does not know, both do not commit an offense. When the three karmans are completed, the upādhyāya incurs a fall [prāyaścittika]. If midway, or the motion is not yet completed, or if performing the preparatory acts, or shaving the head, or gathering the saṃgha, for the upādhyāya all are duṣkṛtas, and likewise for the assembled saṃgha. For bhikṣuṇīs it is a prāyaścittika. There is no offense: if one did not know beforehand, trusting the word of the candidate, or a bystander testifies, or trusting the word of the parents. If after receiving the ordination one doubts, the Buddha said: "One should count the months and years in the womb, count intercalary months, or count all fourteenth-day precept recitations as the count of years; if full, it is permitted.")
