(1) باب تَحْرِيمِ الْخَمْرِ وَبَيَانِ أَنَّهَا تَكُونُ مِنْ عَصِيرِ الْعِنَبِ وَمِنَ التَّمْرِ وَالْبُسْرِ وَالزَّبِيبِ وَغَيْرِهَا مِمَّا يُسْكِرُ
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.
