"While I was taking care of a group of people, including my paternal uncles, and I was the youngest of them, a man came and said: 'Khamr has been forbidden.' I was taking care of them, and was pouring Fadikh (date-wine) for them. They said: 'Pour it away.' So I poured it away." I (the narrator) said to Anas: "What is that?" He said: "Unripe dates and dried dates." Abu Bakr bin Anas said: "That was their wine in those days." And Anas did not deny that. (Using translation from Nasāʾī 5541)  

بَيْنَا أَنَا قَائِمٌ عَلَى الْحَيِّ وَأَنَا أَصْغَرُهُمْ سِنًّا عَلَى عُمُومَتِي إِذْ جَاءَ رَجُلٌ فَقَالَ إِنَّهَا قَدْ حُرِّمَتِ الْخَمْرُ وَأَنَا قَائِمٌ عَلَيْهِمْ أَسْقِيهِمْ مِنْ فَضِيخٍ لَهُمْ فَقَالُوا اكْفَأْهَا فَكَفَأْتُهَا فَقُلْتُ لِأَنَسٍ مَا هُوَ؟ قَالَ «الْبُسْرُ وَالتَّمْرُ» قَالَ أَبُو بَكْرِ بْنُ أَنَسٍ كَانَتْ خَمْرُهُمْ يَوْمَئِذٍ فَلَمْ يُنْكِرْ أَنَسٌ  

[Machine] And Anas said: "Indeed, alcohol has been prohibited, and on that day most of their alcohol was made from dates."  

وَقَالَ أَنَسٌ لَقَدْ حُرِّمَتِ الْخَمْرُ وَإِنَّ عَامَّةَ خَمْرِهِمْ يَوْمَئِذٍ الْفَضِيخُ  

"When Khamr was forbidden, their drink was (made from) unripe dates and dried dates." (Using translation from Nasāʾī 5543)  

«حُرِّمَتِ الْخَمْرُ حِينَ حُرِّمَتْ وَإِنَّهُ لَشَرَابُهُمُ الْبُسْرُ وَالتَّمْرُ»
