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.
