Sahih al-Bukhari 5622Book 74, Hadith 48
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.
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."
