佛說目連問戒律中五百輕重事經 2.102

2.102

問：「未滿五臘，得並入誦律不？」答：「不得。為可粗教誡而已。若誦犯捨墮，大戒不滅沙彌戒故。」「是沙彌非？」答：「非。」

Question: "Before completing five rains, may one enter along with others to recite the Vinaya?" Answer: "He may not. One may only roughly give him admonitions and instructions. If he recites it, he commits a naiḥsargika-pāyattika, because the full precepts do not obliterate the śrāmaṇera precepts." [Question:] "Is he a śrāmaṇera or not?" Answer: "He is not."
