It is narrated from Abu Tufail, he says: We said to Sayyiduna Ali (may Allah be pleased with him): Tell us about something which the Messenger of Allah (peace and blessings be upon him) granted only to you. He said: The Prophet (peace and blessings be upon him) did not tell me any secret which he concealed from the people, except that I heard him say: May Allah curse the one who sacrifices for other than Allah; may Allah curse the one who gives shelter to an innovator; may Allah curse the one who curses his parents; and may Allah curse the one who changes the landmarks of the earth.
