四分律比丘含注戒本 2.265

2.265

The Buddha was in the country of Śrāvastī. A wife quarrelled with her mother-in-law and was returning to Vaiśālī. At that time, Aniruddha wished to go to that country, and this woman became his companion. Her husband then pursued and caught them, beating Aniruddha almost to the point of cutting off his life-faculty. The bhikṣus reported the matter to the Buddha, who thereupon rebuked [them] and laid down this rule.
