大比丘三千威儀 1.75

1.75

有五事：一者不得著禮佛、二者不得著入眾坐、三者不得著上佛塔上、四者不得著經行、五者天雨不得著自得分衛。

There are five matters: first, one must not wear it to pay homage to the Buddha; second, one must not wear it to enter the seating of the assembly; third, one must not wear it to ascend the Buddha's stūpa; fourth, one must not wear it for caṅkramaṇa; fifth, when it rains, one must not wear it to go on piṇḍapāta oneself.
