四分律行事鈔資持記 2.1104

2.1104

七中。律緣瓶沙王妹有子，於外道出家，詣僧坊設食故佛開之。疏云：將化入道，故開受供。

In the seventh [case]: The Vinaya origin is that King Bimbisāra's sister had a son who went forth among the non-Buddhists; he came to the monastery to provide food, so the Buddha allowed it. The Commentary states: Because he was about to be converted and enter the Way, he was allowed to accept the offering.
