四分律比丘含注戒本 1.132

1.132

The Buddha was in the country of Śrāvastī. The bhikṣu Kālu[dayin], because the Buddha had formulated the preceding rule, then waited outside the gate for women, led them into his room, and grasped and stroked them with his hands; those who enjoyed it laughed, while those who did not enjoy it became angry and verbally abused him. The bhikṣus raised the fault and addressed the Buddha, who then assembled the saṃgha and formulated the precept.
