四分律比丘含注戒本 2.742

2.742

佛在舍衛。外道在道行，因止息，忘千兩金而去。比丘見之，為持去，以金還之。便言金少，王斷罰謫，奪金入官。比丘舉過白佛，便訶制此戒。

The Buddha was in Śrāvastī. An outside follower of other teachings was walking along the road, stopped to rest, and departed leaving behind a thousand liang of gold. A bhikṣu saw it, carried it away for him, and returned the gold to him. [The traveler] then claimed that the gold was less; the king passed judgment, penalized him, and confiscated the gold for the court. The bhikṣus reported this fault to the Buddha, who thereupon rebuked him and formulated this precept.
