Sahih Muslim Book - 36, Hadith - 5133

وحَدَّثَنَا يَحْيَى بْنُ أَيُّوبَ ، حَدَّثَنَا ابْنُ عُلَيَّةَ ، قَالَ: وَأَخْبَرَنَا سُلَيْمَانُ التَّيْمِيُّ ، حَدَّثَنَا أَنَسُ بْنُ مَالِكٍ ، قَالَ: إِنِّي لَقَائِمٌ عَلَى الْحَيِّ عَلَى عُمُومَتِي أَسْقِيهِمْ مِنْ فَضِيخٍ لَهُمْ وَأَنَا أَصْغَرُهُمْ سِنًّا ، فَجَاءَ رَجُلٌ ، فَقَالَ: إِنَّهَا قَدْ حُرِّمَتِ الْخَمْرُ ، فَقَالُوا: اكْفِئْهَا يَا أَنَسُ ، فَكَفَأْتُهَا. قَالَ: قُلْتُ لأَنَسٍ: مَا هُوَ ؟ قَالَ: بُسْرٌ وَرُطَبٌ. قَالَ: فَقَالَ أَبُو بَكْرِ بْنُ أَنَسٍ: كَانَتْ خَمْرَهُمْ يَوْمَئِذٍ.قَالَ سُلَيْمَانُ: وَحَدَّثَنِي رَجُلٌ ، عَنْ أَنَسِ بْنِ مَالِكٍ ، أَنَّهُ قَالَ ذَلِكَ أَيْضًا.

Anas bin Malik said: "I was looking after the uncles (elders) of my tribe, pouring date wine for them, and I was the youngest of them. Then a man came and said: 'Khamr has been forbidden.' They said: 'Spill it out, O Anas,' so I spilled it out." I (the sub narrator) said to Anas: "What was it?" He said: "Unripe dates and fresh dates." And Abu Bakr bin Anas said: "That was their Khamr in those days."
