37- سَمِعتُ أبَا نَصْرٍ مُحَمَّد بن الحَسَن الكَرْخِيِّ الكاتِبُ يَقُولُ رَأيْتُ عَلَى قَبْرِ دِعْبِل بْنِ عَلِيٍّ الخُزاعِيّ مَكْتوباً: أَعَدَّ للهِ يَوْمَ يَلْقَاهُ يَقُولُ مُخْلِصَاً عَسَاهُ اللهُ مَوْلاَهُ وَالرَّسُولُ وَمَنْ دِعْبِلٌ أنْ لاَ إلَهَ إلاَّ هُو بِهَا يَرْحَمُهُ فِي القِيَامَةِ اللهُ بَعْدَهُمَا فَالْوَصِيُّ مَوْلاَهُ
