أَخْبَرَنَا قُتَيْبَةُ، قَالَ حَدَّثَنَا اللَّيْثُ، عَنْ عَطَاءٍ، عَنْ جَابِرٍ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم أَنَّهُ نَهَى أَنْ يُنْبَذَ الزَّبِيبُ وَالتَّمْرُ جَمِيعًا وَنَهَى أَنْ يُنْبَذَ الْبُسْرُ وَالتَّمْرُ 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.'"
