[369] Now at that time the Mettiya-Bhummajaka bhikkhus, thinking, "The Blessed One has prohibited complaining (ujjhāpanaka); by this much the bhikkhus will hear," criticized (khīyanti) the Venerable Dabba Mallaputta in the vicinity of the bhikkhus, saying, "Dabba Mallaputta assigns lodgings out of favoritism and designates meals out of favoritism."
Those bhikkhus who were of few wishes … complained, criticized, and spread it about, saying, "How can the Mettiya-Bhummajaka bhikkhus criticize the Venerable Dabba Mallaputta?" Then those bhikkhus reported this matter to the Blessed One.
Then the Blessed One … questioned the Mettiya-Bhummajaka bhikkhus: "Is it true, as they say, bhikkhus, that you criticize Dabba Mallaputta?"
"It is true, Blessed One."
The Buddha, the Blessed One, rebuked them: "How can you, foolish men, criticize Dabba Mallaputta? This, foolish men, is not for the arousing of confidence in those without confidence … And thus, bhikkhus, you should recite this training rule:
"In complaining, in criticizing, there is an offense entailing expiation (pācittiya)."
