حَدَّثَنَا مُحَمَّدُ بْنُ الْمُثَنَّى، وَابْنُ، بَشَّارٍ قَالاَ حَدَّثَنَا مُحَمَّدُ بْنُ جَعْفَرٍ، حَدَّثَنَا شُعْبَةُ، سَمِعْتُ أَبَا إِسْحَاقَ، يُحَدِّثُ عَنْ أَبِي الأَحْوَصِ، عَنْ عَبْدِ اللَّهِ بْنِ مَسْعُودٍ، قَالَ إِنَّ مُحَمَّدًا صلى الله عليه وسلم قَالَ ‏
"‏ أَلاَ أُنَبِّئُكُمْ مَا الْعَضْهُ هِيَ النَّمِيمَةُ الْقَالَةُ بَيْنَ النَّاسِ ‏"‏ ‏.‏ وَإِنَّ مُحَمَّدًا صلى الله عليه وسلم قَالَ ‏"‏ إِنَّ الرَّجُلَ يَصْدُقُ حَتَّى يُكْتَبَ صِدِّيقًا وَيَكْذِبُ حَتَّى يُكْتَبَ كَذَّابًا ‏"‏ ‏.‏
