四分律比丘含注戒本 3.21

3.21

佛在羅閱城。居士夫婦俱得見諦，無所愛惜，乃至身肉。供養既多，衣食乏盡。居士譏嫌，比丘舉過。佛令白二制斷比丘，後富更解，便制此戒。

The Buddha was in Rājagṛha. A householder and his wife had both attained the vision of truth, and had no attachment or stinginess, even toward their own flesh. Since their offerings were vast, their clothing and food were completely exhausted. The householders criticized and mocked them, and the bhikṣus reported the fault. The Buddha ordered that by a jñaptidvitīya-karman the bhikṣus be prohibited [from accepting food there]; later, when they became wealthy again, it was revoked. He then formulated this precept.
