四分律比丘含注戒本 2.784

2.784

佛在羅閱祇。有信工師為比丘作骨、牙、角針筒，因廢業，無衣食，世人譏言：「望其得福，而反得殃。」比丘舉過白佛，因訶制戒。

The Buddha was in Rājagṛha. A faithful craftsman made needle cases of bone, ivory, and horn for the bhikṣus, and consequently abandoned his trade and lacked clothing and food. People of the world criticized them, saying: "Expecting to obtain merit, instead he incurred misfortune." The bhikṣus reported this fault to the Buddha, who thereupon rebuked them and formulated the precept.
