四分律比丘含注戒本 1.254

1.254

佛在羅閱祇。時，提婆達故執五法：盡形乞食，著糞掃衣，常受露坐，不食穌鹽、魚及肉。以教比丘。眾僧諫時，伴黨比丘助破諫僧。比丘舉過，佛訶責已，因制此戒。

The Buddha was in Rājagṛha. At that time, Devadatta obstinately held to five practices: begging for food throughout one's life, wearing rag-robes, always sitting in the open, and not eating ghee, salt, fish, or meat. He taught these to the bhikṣus. When the Saṃgha admonished him, partisan bhikṣus assisted him in splitting [the Saṃgha] and resisted the admonishing Saṃgha. Bhikṣus brought up the fault, and after the Buddha rebuked him, he laid down this precept.
