From Sahih Bukhari (Hadith 4617):
Narrated Anas bin Malik:We had no alcoholic drink except that which was produced from dates and which you call Fadikh. While I was standing offering drinks to Abu Talha and so-and-so and so-and-so, a man came and said, "Has the news reached you? They said, "What is that?" He said, "Alcoholic drinks have been prohibited. They said, "Spill (the contents of these pots, O Anas!" Then they neither asked about it (alcoholic drinks) nor returned to it after the news from that man
