سنن النسائي

It was narrated that Anas said: "I was pouring (wine) for Abu Talhah, Ubayy bin Ka'b and Abu Dujanah among a group of Ansar when a man came in and said: 'Something new has happened; the prohibition of Khamr has been revealed.' So we poured it away." He said: "The only intoxicant in those days was Fadikh, a mixture of unripe dates and dried dates." And Anas said: "Khamr was forbidden, and most of their Khamr in those days was Fadikh."
