Mu'abad Jahani says that Sayyiduna Muawiyah (may Allah be pleased with him) narrated fewer hadiths from the Messenger of Allah (peace and blessings be upon him), and he would rarely leave out these words (or the narrator said:) he would mention them in the Friday sermons, that the Noble Prophet (peace and blessings be upon him) said: "When Allah intends good for someone, He grants him understanding of the religion. Wealth is sweet, lush, and attractive; whoever acquires it rightfully, it will be blessed for him. And avoid praising one another, for doing so is akin to slaughtering (i.e., it destroys)."
