五分比丘尼戒本 1.42

1.42

「若比丘尼，從非親里居士居士婦乞衣，除因緣，尼薩耆波逸提。因緣者，奪衣、失衣、燒衣、漂衣、壞衣、是名因緣。

"If a bhikṣuṇī begs a robe from an unrelated male or female householder, except on the proper occasion, it is a niḥsargika-pāyattika. The proper occasions are: when robes have been robbed, robes lost, robes burnt, robes swept away [by water], or robes ruined; these are called the proper occasions.
