Unripe-date drink and ripe-date drink should not be mixed if it is an intoxicant, and two cooked foods should not be put in one dish
حَدَّثَنَا مُسْلِمٌ، حَدَّثَنَا هِشَامٌ، أَخْبَرَنَا يَحْيَى بْنُ أَبِي كَثِيرٍ، عَنْ عَبْدِ اللَّهِ بْنِ أَبِي قَتَادَةَ، عَنْ أَبِيهِ، قَالَ نَهَى النَّبِيُّ صلى الله عليه وسلم أَنْ يُجْمَعَ بَيْنَ التَّمْرِ وَالزَّهْوِ، وَالتَّمْرِ وَالزَّبِيبِ، وَلْيُنْبَذْ كُلُّ وَاحِدٍ مِنْهُمَا عَلَى حِدَةٍ.
Narrated Abu Qatada: The Prophet (ﷺ) 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 )
