四分律比丘含注戒本 2.507

2.507

除手脚已，若杖，若拂柄、戶鑰、餘物擊攊，吉羅。不犯者：若不故作；若眠，觸令覺。若出入行來，若掃地，誤以杖頭觸他者，無犯。

Apart from the hands and feet, if one tickles with a staff, a whisk-handle, a key, or other objects, it is a duṣkṛta. There is no offence: if one does not do so intentionally; if someone is asleep and one touches him to awaken him; or while walking back and forth, or sweeping the ground, one mistakenly touches another with the tip of a staff—there is no offence.
