Sahih Muslim
وَحَدَّثَنِي أَبُو بَكْرِ بْنُ إِسْحَاقَ، حَدَّثَنَا عَفَّانُ بْنُ مُسْلِمٍ، حَدَّثَنَا أَبَانٌ الْعَطَّارُ، حَدَّثَنَا يَحْيَى بْنُ أَبِي كَثِيرٍ، حَدَّثَنِي عَبْدُ اللَّهِ بْنُ أَبِي قَتَادَةَ، عَنْ أَبِيهِ، أَنَّ نَبِيَّ اللَّهِ صلى الله عليه وسلم نَهَى عَنْ خَلِيطِ التَّمْرِ وَالْبُسْرِ وَعَنْ خَلِيطِ الزَّبِيبِ وَالتَّمْرِ وَعَنْ خَلِيطِ الزَّهْوِ وَالرُّطَبِ وَقَالَ " انْتَبِذُوا كُلَّ وَاحِدٍ عَلَى حِدَتِهِ " .
'Abdullah b. Abu Qatada, on the authority of his father, reported Allah's Apostle (ﷺ) forbidding the preparation of the mixture of ripe dates and unripe dates, and the mixture of grapes and dates, and that of nearly ripe dates and fresh dates but the Prophet said: Prepare the Nabidh from each one of them separately.
