四分律比丘含注戒本 2.672

2.672

(If indistinct, it is a duṣkṛta. Reviling the Vinaya is a prāyaścittika. Reviling the Abhidharma and other sūtras is a duṣkṛta. Bhikṣuṇīs commit the same offence. As for the non-offences: if one says, "First recite the Abhidharma, and afterwards recite the Vinaya," and the same for other sūtras; if one is sick, "Wait until recovered to recite the Vinaya"; "One should vigorously seek means to achieve the four śramaṇa fruits within the Buddha's Dharma, and afterwards recite the Vinaya," without wishing to destroy the Dharma; or if one speaks in error—all are permitted.)
