過前求雨衣戒過前用戒二十七　此兩戒合制。依多論亦過前求過前用二俱尼薩耆。所以不聽。過前求用者。然此雨衣資身要用。是以開聽時中乞用。今時未至類乞先用　長己貪結違反聖教。是以聖制　過前求別緣有五。一是雨衣。二是過前求。三為己。彼與。五領受便犯。過前用戒別緣具四。一是己雨衣。二非時中得。三時前受持。四過前用犯。此二戒同是雨衣義容相由生罪。是以合制。已下正明戒本。此戒因六群比丘常求雨衣。佛便制戒。

The Precept against Seeking a Rains-Robe Before the Time and Using It Before the Time (the twenty-seventh). These two precepts are formulated together. According to the Sarvāstivāda-vinaya-vibhāṣā, both seeking before the time and using before the time are niḥsargika. Why are seeking and using before the time not permitted? This rains-robe is an essential item for sustaining the body; therefore, it is permitted to be begged and used during its proper season. Now, when the season has not yet arrived, begging and using it beforehand increases one's greed and violates the noble teachings; therefore the Noble One formulated [the precept]. The specific conditions for seeking before the time are five: first, it is a rains-robe; second, seeking it before the time; third, doing so for oneself; fourth, the other gives it; fifth, accepting it, whereupon the offense is incurred. The precept against using it before the time possesses four specific conditions: first, it is one's own rains-robe; second, obtaining it out of season; third, formally resolving upon it before the season; fourth, using it before the time, incurring the offense. Because both precepts concern the rains-robe and their meanings permit them to give rise to offenses mutually dependent on each other, they are formulated together. The following directly explains the text of the precept. This precept arose because the group of six bhikṣus constantly sought rains-robes; the Buddha then formulated the precept.
