حَدَّثَنَا مُحَمَّدُ بْنُ يَحْيَى بْنِ فَيَّاضٍ، حَدَّثَنَا أَبِي ح، وَحَدَّثَنَا ابْنُ الْمُثَنَّى، حَدَّثَنَا يَحْيَى بْنُ الْفَيَّاضِ، حَدَّثَنَا هَمَّامٌ، عَنْ قَتَادَةَ، قَالَ لَيْسَ فِي التَّمْرِ حُكْرَةٌ ‏.‏ قَالَ ابْنُ الْمُثَنَّى قَالَ عَنِ الْحَسَنِ فَقُلْنَا لَهُ لاَ تَقُلْ عَنِ الْحَسَنِ ‏.‏ قَالَ أَبُو دَاوُدَ هَذَا الْحَدِيثُ عِنْدَنَا بَاطِلٌ ‏.‏ قَالَ أَبُو دَاوُدَ كَانَ سَعِيدُ بْنُ الْمُسَيَّبِ يَحْتَكِرُ النَّوَى وَالْخَبَطَ وَالْبِزْرَ سَمِعْتُ أَحْمَدَ بْنَ يُونُسَ يَقُولُ سَأَلْتُ سُفْيَانَ عَنْ كَبْسِ الْقَتِّ فَقَالَ كَانُوا يَكْرَهُونَ الْحُكْرَةَ وَسَأَلْتُ أَبَا بَكْرِ بْنَ عَيَّاشٍ فَقَالَ اكْبِسْهُ ‏.‏
