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.
