大比丘三千威儀 1.49

1.49

復有五事：一者不得上樹；二者不得持梨擲與人；三者不得持水灑人；四者水中有虫不得飲若洗；五者人罵比丘，比丘不得報。

There are further five matters: first, one must not climb trees; second, one must not take pears and throw them to others; third, one must not take water and sprinkle it on others; fourth, if there are insects in water, one must not drink it or wash with it; fifth, if someone insults a bhikṣu, the bhikṣu must not retaliate.
