四分律比丘含注戒本 2.351

2.351

佛在羅閱城。時人民節會，難陀、跋難陀二釋子共看伎，并受飲食，向暮還山。迦留陀夷夜入城乞食，女人雷電中見，稱言：「鬼！鬼！」比丘以過白佛，訶制此戒。

The Buddha was in Rājagṛha. At that time, the people were holding a festival. The two Śākyan sons, Nanda and Upananda, went together to watch theatrical performers, and also accepted food and drink, returning to the mountain toward evening. Kālodayin entered the city at night to beg for food, and a woman saw him in a flash of lightning and cried out: 'A ghost! A ghost!' The bhikṣus reported this fault to the Buddha, who rebuked them and formulated this precept.
