36/1. Chapter:
The prohibition of Khamr, which may be made from the juice of grapes, dried dates, unripe dates, raisins and other things that intoxicate
Sahih Muslim
وَحَدَّثَنِي أَبُو الطَّاهِرِ، أَحْمَدُ بْنُ عَمْرِو بْنِ سَرْحٍ أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ وَهْبٍ، أَخْبَرَنِي عَمْرُو بْنُ الْحَارِثِ، أَنَّ قَتَادَةَ بْنَ دِعَامَةَ، حَدَّثَهُ أَنَّهُ، سَمِعَ أَنَسَ بْنَ مَالِكٍ، يَقُولُ إِنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم نَهَى أَنْ يُخْلَطَ التَّمْرُ وَالزَّهْوُ ثُمَّ يُشْرَبَ وَإِنَّ ذَلِكَ كَانَ عَامَّةَ خُمُورِهِمْ يَوْمَ حُرِّمَتِ الْخَمْرُ .
Anas b. Malik is reported to have said that Allah's Messenger (ﷺ) had forbidden to mixture fresh dates and unripe dates and then drinking (the wine prepared out of it), and that was their common intoxicant when liquor was prohibited.
