البيهقي:٢١١٥٩ – وَأَخْبَرَنَا أَبُو الْحَسَنِ عَلِيُّ بْنُ مُحَمَّدٍ الْمُقْرِئُ أنبأ الْحَسَنُ بْنُ مُحَمَّدِ بْنِ إِسْحَاقَ ثنا يُوسُفُ بْنُ يَعْقُوبَ ثنا أَحْمَدُ بْنُ عِيسَى ثنا ابْنُ وَهْبٍ أَخْبَرَنِي ابْنُ لَهِيعَةَ وَعَمْرُو بْنُ الْحَارِثِ عَنْ يَزِيدَ بْنِ أَبِي حَبِيبٍ عَنْ سِنَانٍ يَعْنِي ابْنَ سَعْدٍ عَنْ أَنَسِ بْنِ مَالِكٍ

عَنِ النَّبِيِّ ﷺ أَنَّهُ قَالَ: «أَتَدْرُونَ مَا الْعِضَةُ؟» قَالُوا: اللهُ وَرَسُولُهُ أَعْلَمُ، قَالَ: «نَقْلُ الْحَدِيثِ مِنْ بَعْضِ النَّاسِ إِلَى بَعْضٍ لِيُفْسِدَ بَيْنَهُمْ»
