البيهقي:١٦٣٨٥أَخْبَرَنَا أَبُو سَعِيدِ بْنُ أَبِي عَمْرٍو ثنا أَبُو الْعَبَّاسِ الْأَصَمُّ ثنا بَحْرُ بْنُ نَصْرٍ ثنا عَبْدُ اللهِ بْنُ وَهْبٍ قَالَ وَأَخْبَرَنِي ابْنُ أَبِي ذِئْبٍ عَنْ سَعِيدِ بْنِ الْمُسَيِّبِ وَسُلَيْمَانَ بْنِ يَسَارٍ أَنَّهُمَا قَالَا لَا تَحْمِلُ الْعَاقِلَةُ إِلَّا ثُلُثَ الدِّيَةِ فَصَاعِدًا كَذَا قَالَا وَذَهَبَ الشَّافِعِيُّ إِلَى أَنَّهَا تَحْمِلُ كُلَّ مَا كَثُرَ وَقَلَّ؛
