حَدَّثَنَا أَحْمَدُ بْنُ عَمْروِ بْنِ السَّرْحِ أَخْبَرَنَا ابْنُ وَهْبٍ حَدَّثَنِي عَبْدُ الرَّحْمَنِ بْنُ زِيَادٍ عَنْ عَبْدِ الرَّحْمَنِ بْنِ رَافِعٍ التَّنُوخِيِّ عَنْ عَبْدِ اللَّهِ بْنِ عَمْرِو بْنِ الْعَاصِ أَنَّ رَسُولَ اللَّهِ صَلَّی اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ الْعِلْمُ ثَلَاثَةٌ وَمَا سِوَی ذَلِکَ فَهُوَ فَضْلٌ آيَةٌ مُحْکَمَةٌ أَوْ سُنَّةٌ قَائِمَةٌ أَوْ فَرِيضَةٌ عَادِلَةٌ
