Musnad Abu Ya'la al-Mawsili 155:84

Abu Khaythama narrated to us, Quraysh ibn Anas narrated to us, from Muhammad ibn ‘Amr, from Abu Salamah, from Abu Hurayrah, who said: The Messenger of Allah (ﷺ) said: "The best of you is the best of you to my family after me." Abu Khaythama said: People say "to his family," but he said "to my family."
