Sunan an-Nasai
أَخْبَرَنَا وَاصِلُ بْنُ عَبْدِ الأَعْلَى، عَنِ ابْنِ فُضَيْلٍ، عَنْ أَبِي إِسْحَاقَ، عَنْ حَبِيبِ بْنِ أَبِي ثَابِتٍ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، عَنِ ابْنِ عَبَّاسٍ، قَالَ نَهَى رَسُولُ اللَّهِ صلى الله عليه وسلم عَنِ الدُّبَّاءِ وَالْحَنْتَمِ وَالْمُزَفَّتِ وَالنَّقِيرِ وَعَنِ الْبُسْرِ وَالتَّمْرِ أَنْ يُخْلَطَا وَعَنِ الزَّبِيبِ وَالتَّمْرِ أَنْ يُخْلَطَا وَكَتَبَ إِلَى أَهْلِ هَجَرَ " أَنْ لاَ تَخْلِطُوا الزَّبِيبَ وَالتَّمْرَ جَمِيعًا ".
It was narrated that Ibn 'Abbas said: "The Messenger of Allah [SAW] forbade Ad-Dubba', Al-Hantam, Al-Muzaffat, and An-Naqir, and that Al-Busr be mixed with dried dates, and that raisins be mixed with dried dates, and he wrote to the people of Hajar saying: 'Do not mix raisins and dried dates together.'"
