Sahih Muslim , Book 36, Hadith 9 (In-Book) ⓘ

Anas b. Malik reported I was serving wine to Abu Talha, and Abu Dujana. and Mu'adh b. jabal admidst a group of Ansar when a visitor came to us and said There is a fresh news; the (verses) concerning the prohibition of liquor have been revealed. So we spilt it on that day; and it was a mixture of dry dates and fresh dates. Anas b. Malik said: Whil Khamr was declared unlawful, the common liquor of theirs was then a mixture of dry dates and fresh dates.

وَحَدَّثَنَا يَحْيَى بْنُ أَيُّوبَ، حَدَّثَنَا ابْنُ عُلَيَّةَ، قَالَ وَأَخْبَرَنَا سَعِيدُ بْنُ أَبِي عَرُوبَةَ، عَنْ قَتَادَةَ، عَنْ أَنَسِ بْنِ مَالِكٍ، قَالَ كُنْتُ أَسْقِي أَبَا طَلْحَةَ وَأَبَا دُجَانَةَ وَمُعَاذَ بْنَ جَبَلٍ فِي رَهْطٍ مِنَ الأَنْصَارِ فَدَخَلَ عَلَيْنَا دَاخِلٌ فَقَالَ حَدَثَ خَبَرٌ نَزَلَ تَحْرِيمُ الْخَمْرِ ‏.‏ فَكَفَأْنَاهَا يَوْمَئِذٍ وَإِنَّهَا لَخَلِيطُ الْبُسْرِ وَالتَّمْرِ ‏.‏ قَالَ قَتَادَةُ وَقَالَ أَنَسُ بْنُ مَالِكٍ لَقَدْ حُرِّمَتِ الْخَمْرُ وَكَانَتْ عَامَّةُ خُمُورِهِمْ يَوْمَئِذٍ خَلِيطَ الْبُسْرِ وَالتَّمْرِ ‏.‏
