البيهقي:٩٠أَخْبَرَنَا أَبُو الْحَسَنِ مُحَمَّدُ بْنُ مُحَمَّدٍ الْفَقِيهُ أنبأ أَبُو سَعِيدٍ عَبْدُ اللهِ بْنُ مُحَمَّدِ بْنِ عَبْدِ الْوَهَّابِ ثنا مُحَمَّدُ بْنُ أَيُّوبَ أنبأ مُسْلِمٌ ثنا هِشَامٌ ثنا قَتَادَةُ قَالَ سَأَلَ دَاوُدُ السَّرَّاجُ الْحَسَنَ عَنْ جُلُودِ النُّمُورِ وَالسَّمُورِ تُدْبَغُ بِالْمِلْحِ؟ فَقَالَ دِبَاغُهَا طَهُورُهَا قَالَ الشَّيْخُ وَقَدْ رَوَى عَمْرُو بْنُ عُبَيْدٍ عَنِ الْحَسَنِ فِي صُوفِ الْمَيْتَةِ اغْسِلْهُ وَرُوِيَ عَنْ عَطَاءٍ أَنَّهُ كَرِهَ ذَلِكَ وَرُوِيَ
