البيهقي:٢٠٨٢٧أَخْبَرَنَا أَبُو الْحَسَنِ عَلِيُّ بْنُ مُحَمَّدٍ الْمُقْرِئُ أنبأ الْحَسَنُ بْنُ مُحَمَّدِ بْنِ إِسْحَاقَ ثنا يُوسُفُ بْنُ يَعْقُوبَ الْقَاضِي ثنا عَمْرُو بْنُ مَرْزُوقٍ ثنا شُعْبَةُ عَنْ سَلَمَةَ بْنِ كُهَيْلٍ عَنْ مُصْعَبِ بْنِ سَعْدٍ عَنْ أَبِيهِ قَالَ

الْمُسْلِمُ يُطْبَعُ عَلَى كُلِّ الطَّبِيعَةِ غَيْرَ الْخِيَانَةِ وَالْكَذِبِ هَذَا مَوْقُوفٌ وَهُوَ الصَّحِيحُ وَقَدْ رُوِيَ مَرْفُوعًا
