俱舍論記 25.53

25.53

「毘婆沙師至亦有退義」者，廣諍既訖，結歸本宗。若依《宗輪論》，大眾部等預流者有退義，阿羅漢無退義。

"The Vibhāṣā masters […] also have the principle of falling away": the extensive dispute having ended, [the treatise] concludes by returning to its own school. According to the Samayabhedoparacanacakra, for the Mahāsāṃghika and other schools, stream-enterers have the principle of falling away, while arhats do not have the principle of falling away.
