Arabic

قَالَ أَبُو حَازِمٍ فَسَمِعَنِي النُّعْمَانُ بْنُ أَبِي عَيَّاشٍ، وَأَنَا أُحَدِّثُهُمْ، هَذَا فَقَالَ هَكَذَا سَمِعْتَ سَهْلاً، فَقُلْتُ نَعَمْ‏.‏ قَالَ وَأَنَا أَشْهَدُ، عَلَى أَبِي سَعِيدٍ الْخُدْرِيِّ لَسَمِعْتُهُ يَزِيدُ فِيهِ قَالَ ‏ "‏ إِنَّهُمْ مِنِّي‏.‏ فَيُقَالُ إِنَّكَ لاَ تَدْرِي مَا بَدَّلُوا بَعْدَكَ فَأَقُولُ سُحْقًا سُحْقًا لِمَنْ بَدَّلَ بَعْدِي ‏"‏‏.‏
