Messenger of Allah ﷺ prohibited us that we should mix dry dates with unripe dates or (mix) grapes with dry dates (and prepare Nabidh). He also said: He who amongst you drinks-the rest of the hadith is the same.  

نَهَانَا رَسُولُ اللَّهِ ﷺ أَنْ نَخْلِطَ بُسْرًا بِتَمْرٍ أَوْ زَبِيبًا بِتَمْرٍ أَوْ زَبِيبًا بِبُسْرٍ وَقَالَ مَنْ شَرِبَهُ مِنْكُمْ فَذَكَرَ بِمِثْلِ حَدِيثِ وَكِيعٍ  

"The Messenger of Allah [SAW] forbade mixing Al-Busr with dried dates, or raisins with dried dates, or raisins with Al-Busr, and he said: 'Whoever among you (wants to) drink them, let him drink each one of them on its own: dried dates on their own, or Al-Busr on their own, or raisins on their own."  

نَهَى رَسُولُ اللَّهِ ﷺ أَنْ يُخْلَطَ بُسْرٌ بِتَمْرٍ أَوْ زَبِيبٌ بِتَمْرٍ أَوْ زَبِيبٌ بِبُسْرٍ وَقَالَ مَنْ شَرِبَهُ مِنْكُمْ فَلْيَشْرَبْ كُلَّ وَاحِدٍ مِنْهُ فَرْدًا تَمْرًا فَرْدًا أَوْ بُسْرًا فَرْدًا أَوْ زَبِيبًا فَرْدًا  

The Prophet [SAW] forbade mixing Al-Busr with dried dates, or raisins with dried dates, or raisins with Al-Busr, and he said: "Whoever among you (wants to) drink them, let him drink each one on its own."  

أَنَّ النَّبِيَّ ﷺ نَهَى أَنْ يَخْلِطَ بُسْرًا بِتَمْرٍ أَوْ زَبِيبًا بِتَمْرٍ أَوْ زَبِيبًا بِبُسْرٍ وَقَالَ مَنْ شَرِبَ مِنْكُمْ فَلْيَشْرَبْ كُلَّ وَاحِدٍ مِنْهُ فَرْدًا قَالَ أَبُو عَبْدِ الرَّحْمَنِ هَذَا أَبُو الْمُتَوَكِّلِ اسْمُهُ عَلِيُّ بْنُ دَاوُدَ  

"The Messenger of Allah [SAW] forbade mixing Al-Busr with dried dates, or raisins with dried dates, or raisins with Al-Busr, and he said: 'Whoever among you (wants to) drink them, let him drink each one of them on its own: dried dates on their own, or Al-Busr on their own, or raisins on their own." (Using translation from Nasāʾī 5568)   

أَنَّ رَسُولَ اللهِ ﷺ نَهَى أَنْ نَخْلِطَ بُسْرًا بِتَمْرٍ وَزَبِيبًا بِتَمْرٍ أَوْ زَبِيبًا بِبُسْرٍ وَقَالَ «مَنْ شَرِبَ مِنْكُمْ فَلْيَشْرَبْ كُلَّ وَاحِدٍ مِنْهُ فَرْدًا»
