What does this mean? Help needed please

The text says:
"Our noble prophet said “Prosperity has ten parts , nine parts of which are in seclusion from people and one is in silence”.

A quick research on this saying in English attributes it to some Imam, not the prophet.
A quick research in Arabic leads to discussions about the weak nature of this alleged Hadith.

Obviously, misinformation also hits religious messages and people circulate a whole load of nonsense without checking trusted sources first.
