四分比丘戒本疏 2.46

2.46

第十四、露處敷僧氈褥犯也。若擬速還，暫出未犯。若心永去，出門即犯。

Fourteenth, the precept against spreading the saṃgha's felt mats or mattresses in the open air: one commits an offence. If one intends to return quickly and goes out only temporarily, one does not yet commit an offence. If in one's mind one departs for good, as soon as one exits the door one commits an offence.
