Sahih al-Bukhari 5622
Narrated Anas:
I was waiting on my uncles, serving them with an alcoholic drink prepared from dates, and I was the 
youngest of them. (Suddenly) it was said that alcoholic drinks had been prohibited. So they said (to 
me), 'Throw it away." And I threw it away The sub-narrator said: I asked Anas what their drink was 
(made from), He replied, "(From) ripe dates and unripe dates."
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا مُعْتَمِرٌ، عَنْ أَبِيهِ، قَالَ سَمِعْتُ أَنَسًا ـ رضى الله عنه ـ قَالَ كُنْتُ قَائِمًا عَلَى الْحَىِّ أَسْقِيهِمْ ـ عُمُومَتِي وَأَنَا أَصْغَرُهُمُ ـ الْفَضِيخَ، فَقِيلَ حُرِّمَتِ الْخَمْرُ‏.‏ فَقَالَ أَكْفِئْهَا‏.‏ فَكَفَأْنَا‏.‏ قُلْتُ لأَنَسٍ مَا شَرَابُهُمْ قَالَ رُطَبٌ وَبُسْرٌ‏.‏ فَقَالَ أَبُو بَكْرِ بْنُ أَنَسٍ وَكَانَتْ خَمْرَهُمْ‏.‏ فَلَمْ يُنْكِرْ أَنَسٌ‏.‏ وَحَدَّثَنِي بَعْضُ أَصْحَابِي أَنَّهُ سَمِعَ أَنَسًا يَقُولُ كَانَتْ خَمْرَهُمْ يَوْمَئِذٍ‏.‏
