Al-Adab Al-Mufrad 17
Abu't-Tufayl said, "'Ali was asked, 'Did the Prophet ﷺ give you something special which he did not give to anyone else?' He replied, 'The Messenger of Allah ﷺ did not give me anything special which he did not give to everyone else except for what I have in my sword scabbard.' He brought out a piece of paper. Written on that paper was:
'Allah curses anyone who sacrifices an animal to something other than Allah. Allah curses anyone who steals a milestone. Allah curses anyone who curses his parents. Allah curses anyone who gives shelter to an innovator.'"
حَدَّثَنَا عَمْرُو بْنُ مَرْزُوقٍ، قَالَ: أَخْبَرَنَا شُعْبَةُ، عَنِ الْقَاسِمِ بْنِ أَبِي بَزَّةَ، عَنْ أَبِي الطُّفَيْلِ قَالَ: سُئِلَ عَلِيٌّ: هَلْ خَصَّكُمُ النَّبِيُّ ﷺ بِشَيْءٍ لَمْ يَخُصَّ بِهِ النَّاسَ كَافَّةً؟ قَالَ: مَا خَصَّنَا رَسُولُ اللهِ ﷺ بِشَيْءٍ لَمْ يَخُصَّ بِهِ النَّاسَ، إِلاَّ مَا فِي قِرَابِ سَيْفِي، ثُمَّ أَخْرَجَ صَحِيفَةً، فَإِذَا فِيهَا مَكْتُوبٌ: لَعَنَ اللَّهُ مَنْ ذَبَحَ لِغَيْرِ اللهِ، لَعَنَ اللَّهُ مَنْ سَرَقَ مَنَارَ الأَرْضِ، لَعَنَ اللَّهُ مَنْ لَعَنَ وَالِدَيْهِ، لَعَنَ اللَّهُ مَنْ آوَى مُحْدِثًا.
