四分律比丘含注戒本 3.75

3.75

佛在舍衛。六群以衣纏頸入白衣舍，居士嫌言：「如居士長者種。」比丘舉過，佛訶制戒。

The Buddha was in Śrāvastī. The group of six entered the homes of laypeople with their robes wrapped around their necks, and householders disparaged them, saying: "They are like the class of householders and elders." The bhikṣus reported the fault, and the Buddha reproached them and laid down the precept.
