四分律比丘含注戒本 2.497

2.497

The Buddha was in Śrāvastī. The group of seventeen were sporting and splashing one another in the Aciravatī River. King Prasenajit and Queen Mallikā saw them from an upper storey. The king said, "Look at those whom you serve!" The queen said, "They have only just gone forth, or they are foolish and unknowing." She then offered rock sugar to the Buddha, who thereupon rebuked [them] and laid down the precept.
