四分比丘戒本疏 2.32

2.32

第二十八、過前受急施衣或過後畜戒。此亦兩戒合制。文言「十日未竟夏三月」者，謂前安居經八十日，猶有十日，未竟九十日也。即當七月六日至十五日，合有十日，此十日中隨於何日得急施，聽受也。以佛當制安居未竟不許受衣，受即犯吉。今此施主有急要緣須遠行等，不得夏竟，故許向前十日內施，名為急施衣也。「受已乃至衣時應畜」者，夏訖之後迦提一月或受五月，並名衣時。衣時之中不須說淨，直爾應畜也。此據七月六日受者，得滿夏後一月五月。若七月七日受者，一月五月已後又更得增一日畜之。若七月八日受者，後增二日畜之。乃至七月十五日受者，後增九日畜之。隨過結犯，如律廣說。

Twenty-eighth: the precept against receiving robe-cloth for urgent distribution in advance of the proper time or keeping it past the limit. This too is a combined formulation of two precepts. As for the text stating 'when ten days remain of the three months of summer': this refers to when eighty days of the earlier retreat have passed and there are still ten days remaining before the ninety days are completed. That corresponds to the period from the sixth day of the seventh month to the fifteenth day, totaling ten days. On whichever of these ten days one obtains [cloth for] urgent distribution, one is permitted to accept it. For the Buddha, when formulating the rule, did not permit receiving robe-cloth when the retreat was not yet completed; receiving it would incur a duṣkṛta. Now this donor has an urgent, pressing reason, such as needing to undertake a long journey, and cannot wait until the summer ends; therefore [the Buddha] permitted offering it in advance within those ten days, which is called 'robe-cloth for urgent distribution.' As for 'having received it, one should keep it up to the robe-season': after the summer retreat ends, the single kārttika month or [a period of] five months is called the 'robe-season.' During the robe-season one does not need to perform vikalpana; one may simply keep it. This is based on receiving it on the sixth day of the seventh month, in which case one may keep it through the full one month or five months after the retreat. If one receives it on the seventh day of the seventh month, one may keep it for an additional day beyond the one month or five months. If one receives it on the eighth day of the seventh month, one may keep it for an additional two days thereafter. Up to receiving it on the fifteenth day of the seventh month, one may keep it for an additional nine days thereafter. In accordance with exceeding [the limit], an offence is established, as explained at length in the Vinaya.
