(1) باب تَحْرِيمِ الْخَمْرِ وَبَيَانِ أَنَّهَا تَكُونُ مِنْ عَصِيرِ الْعِنَبِ وَمِنَ التَّمْرِ وَالْبُسْرِ وَالزَّبِيبِ وَغَيْرِهَا مِمَّا يُسْكِرُ
Anas reported:
I was standing amongst the members of my (tribe) and serving them liquor. The rest of the hadith is the same, but with this variation that Abu Bakr b. Anas said: It was their liquor in those days (prepared from dates), and Anas was present there and he did not deny this (fact) Mu'tamir reported on the authority of his father: A person who was with me told me that he had heard Anas saying that that was their liquor in those days.
