أَخْبَرَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ، قَالَ أَنْبَأَنَا جَرِيرٌ، عَنْ حَبِيبِ بْنِ أَبِي عَمْرَةَ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ نَهَى رَسُولُ اللَّهِ صلى الله عليه وسلم عَنِ الدُّبَّاءِ وَالْمُزَفَّتِ - وَزَادَ مَرَّةً أُخْرَى - وَالنَّقِيرِ وَأَنْ يُخْلَطَ التَّمْرُ بِالزَّبِيبِ وَالزَّهْوُ بِالتَّمْرِ.
