Musannaf Ibn Abi Shayba 13:2058

Abu Bakr narrated to us, he said: Marwan bin Mu'awiyah narrated to us, from Mansur bin Hayyan, from Abu al-Tufayl, who said: I was sitting with Ali when a man came to him and said: "Did the Prophet, may Allah bless him and grant him peace, confide anything to you privately?" He became angry and said: "The Prophet, may Allah bless him and grant him peace, did not confide anything to me privately that he kept hidden from the people, except that he told me four words." He said: "What are they?" He said: "Allah has cursed the one who curses his father, and Allah has cursed the one who sacrifices to other than Allah, and Allah has cursed the one who shelters an innovator, and Allah has cursed the one who alters the landmarks of the land."
