"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.'" (Using translation from Nasāʾī 5557)
نَهَى النَّبِيُّ ﷺ «عَنِ الدُّبَّاءِ وَالْحَنْتَمِ وَالْمُزَفَّتِ وَالنَّقِيرِ وَعَنِ الْبُسْرِ وَالتَّمْرِ أَنْ يُخْلَطَا وَعَنِ الزَّبِيبِ وَالتَّمْرِ أَنْ يُخْلَطَا وَكَتَبَ إِلَى أَهْلِ هَجَرَ أَنْ لَا تَخْلِطُوا الزَّبِيبَ وَالتَّمْرَ جَمِيعًا»
