四分律比丘含注戒本 2.732

2.732

佛在舍衛。末利夫人供佛奉信，勸王信樂，聽諸比丘入宮無障。迦留陀夷到時入宮，夫人拂床，失衣形露。比丘舉過白佛，因訶制戒。

The Buddha was in Śrāvastī. Queen Mallikā made offerings to the Buddha with devout faith, encouraged the king to take faithful delight [in the Dharma], and allowed bhikṣus to enter the palace without obstruction. Kālodayin entered the palace at an inappropriate time; the queen was dusting the bed, her clothes slipped off, and her form was exposed. The bhikṣus reported the fault and informed the Buddha, who thereupon rebuked him and instituted the rule.
