It is disliked to make Nabidh by mixing dried dates and raisins
وَحَدَّثَنِيهِ أَبُو بَكْرِ بْنُ إِسْحَاقَ، حَدَّثَنَا رَوْحُ بْنُ عُبَادَةَ، حَدَّثَنَا حُسَيْنٌ الْمُعَلِّمُ، حَدَّثَنَا يَحْيَى بْنُ أَبِي كَثِيرٍ، بِهَذَيْنِ الإِسْنَادَيْنِ غَيْرَ أَنَّهُ قَالَ " الرُّطَبَ وَالزَّهْوَ وَالتَّمْرَ وَالزَّبِيبَ " .
This hadith has been narrated on the authority of Yahya b. Abu Kathir through these two chains of transmitters but with a slight variation of words.
