Sahih muslim:1997b Chapter: The prohibition of Khamr, which may be made from the juice of grapes, dried dates, unripe dates, raisins and other things that intoxicate Book 36, Hadith 61

Sa’id b. Jubair reported: I asked Ibn ‘Umar about (the preparation of) Nabidh in a green pitcher (besmeared with pitch), whereupon he said that Allah’s Messenger (ﷺ) forbade the (preparation of) Nabidh in green pitcher (besmeared with pitch). I then came to Ibn Abbas and said: Do you hear what Ibn ‘Umar has said? Thereupon he said: What does he say? I said: He stated that Allah’s Messenger (ﷺ) has forbidden the (preparation of) Nabidh in a green pitcher (besmeared with pitch), whereupon he said: Ibn ‘Umar has told the truth. Allah’s Messenger (ﷺ) declared unlawful the preparation of Nabidh in a green pitcher (besmeared with pitch). I said: What is this thing, the Nabidh of a pitcher (Nabidh prepared in a pitcher)? Thereupon, he said: Everything that is prepared in earthen pitcher.
