Mukhtasar Muslim

Abu al-Tufayl Amir bin Wathilah says: I was sitting with Sayyiduna Ali (may Allah be pleased with him) when a man came and said, "Did the Messenger of Allah (peace and blessings be upon him) tell you something secretly?" Upon hearing this, Sayyiduna Ali (may Allah be pleased with him) became angry and said, "The Noble Prophet (peace and blessings be upon him) did not tell me anything that was hidden from others, except that he told me four things." The man said, "O Commander of the Faithful! What are they?" Sayyiduna Ali (may Allah be pleased with him) said that the Noble Prophet (peace and blessings be upon him) said: 1. May Allah curse the one who curses his father. 2. May Allah curse the one who sacrifices for anyone other than Allah. 3. May Allah curse the one who gives shelter to an innovator. 4. And may Allah curse the one who changes the landmarks of the land.
