عَنْ أَبِي الطُّفَيْلِ رَضِيَ اللَّهُ عَنْهُ 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
Abu Tufail says: We said to Sayyiduna Ali (may Allah be pleased with him): Tell us that thing which the Noble Prophet (peace and blessings be upon him) told you people in secrecy. He said: The Noble Prophet (peace and blessings be upon him) did not tell us anything in secrecy that was hidden from the people. However, I heard him (peace and blessings be upon him) saying: Allah curses the one who sacrifices for other than Allah; Allah curses the person who gives shelter to an innovator; Allah curses the man who curses his parents; and Allah curses the person who changes the landmarks of the earth.
