Narrated 'Amir bin Abi 'Amir Al-Ash'ari: from his father who said: "The Messenger of Allah (ﷺ) said: 'Blessed are the tribes of Al-Asad and Al-Ash'arun, they flee not from fighting nor do they pilfer the spoils of war. They are from me and I am from them.'" He ('Amir) said: "So I narrated that to Mu'awiyah, and he said: "This is not how the Messenger of Allah (ﷺ) said it, he said: 'They are from me, and for me.' I said, this is not how my father narrated it to me, rather he narrated to me, saying: 'I heard the Messenger of Allah (ﷺ) saying: "They are from me and I am from them.'" So he said: 'Then you are more knowledgeable of your father's Hadith.'"
