Is "keeping away from people a virtue" an authentic hadith attributed to the Prophet, peace and blessings be upon him?

This statement is not from the words of the Prophet, peace and blessings be upon him, nor has it been narrated by any of the Hadith scholars. Rather, what has been narrated from him, peace and blessings be upon him, contradicts it, which is his saying: "The believer who mixes with people and endures their harm is greater in reward than the one who does not mix with people and does not endure their harm." However, isolation and refraining from mixing with people may be better if a person fears temptation concerning his religion.
