عَنْ أَبِي الطُّفَيْلِ قَالَ قُلْنَا لِعَلِيٍّ رَضِيَ اللَّهُ عَنْهُ أَخْبِرْنَا بِشَيْءٍ أَسَرَّهُ إِلَيْكَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَقَالَ مَا أَسَرَّ إِلَيَّ شَيْئًا كَتَمَهُ النَّاسَ وَلَكِنْ سَمِعْتُهُ يَقُولُ لَعَنَ اللَّهُ مَنْ ذَبَحَ لِغَيْرِ اللَّهِ وَلَعَنَ اللَّهُ مَنْ آوَى مُحْدِثًا وَلَعَنَ اللَّهُ مَنْ لَعَنَ وَالِدَيْهِ وَلَعَنَ اللَّهُ مَنْ غَيَّرَ تُخُومَ الْأَرْضِ يَعْنِي الْمَنَارَ
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.
