Narrated Abu Qatada:
The Prophet forbade the mixing of ripe and unripe dates and also the mixing of dates and raisins (for preparing a syrup) but the syrup of each kind of fruit should be prepared separately. ( One may have such drinks as long as it is fresh )
حَدَّثَنَا مُسْلِمٌ، حَدَّثَنَا هِشَامٌ، أَخْبَرَنَا يَحْيَى بْنُ أَبِي كَثِيرٍ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي قَتَادَةَ، عَنْ أَبِيهِ، قَالَ نَهَى النَّبِيُّ ﷺ أَنْ يُجْمَعَ بَيْنَ التَّمْرِ وَالزَّهْوِ، وَالتَّمْرِ وَالزَّبِيبِ، وَلْيُنْبَذْ كُلُّ وَاحِدٍ مِنْهُمَا عَلَى حِدَةٍ.
