四分律刪補隨機羯磨 2.203

2.203

（《律》中：「比丘受七日出界，為父母、兄姊等至意留，過日；或水陸道斷，遂即過限。佛言：『不失歲。』」《僧祇》云：「若受日在道，不得迂迴，當日若了，即還本界。」）

(In the Vinaya: "A bhikṣu took seven days' leave to go beyond the boundary and was earnestly detained by his parents, elder brothers, or sisters, thereby exceeding the period; or the water or land routes were cut off, so that he exceeded the limit. The Buddha said: 'He does not lose his rains year.'" The Mahāsāṃghika-vinaya states: "If one takes leave and is on the road, one must not make detours; once the business is completed that day, one must immediately return to one's original boundary.")
