Sahih Muslim 1980 d
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.
حَدَّثَنَا مُحَمَّدُ بْنُ عَبْدِ الأَعْلَى، حَدَّثَنَا الْمُعْتَمِرُ، عَنْ أَبِيهِ، قَالَ قَالَ أَنَسٌ كُنْتُ قَائِمًا
 عَلَى الْحَىِّ أَسْقِيهِمْ ‏.‏ بِمِثْلِ حَدِيثِ ابْنِ عُلَيَّةَ غَيْرَ أَنَّهُ قَالَ فَقَالَ أَبُو بَكْرِ بْنُ أَنَسٍ كَانَ خَمْرَهُمْ
 يَوْمَئِذٍ ‏.‏ وَأَنَسٌ شَاهِدٌ فَلَمْ يُنْكِرْ أَنَسٌ ذَاكَ ‏.‏ وَقَالَ ابْنُ عَبْدِ الأَعْلَى حَدَّثَنَا الْمُعْتَمِرُ عَنْ أَبِيهِ
 قَالَ حَدَّثَنِي بَعْضُ مَنْ كَانَ مَعِي أَنَّهُ سَمِعَ أَنَسًا يَقُولُ كَانَ خَمْرَهُمْ يَوْمَئِذٍ ‏.‏
