Sunan an-Nasa'i

It was narrated that Sa'eed bin Jubair said: "I was with Ibn 'Umar when he was asked about Nabidh made in an earthenware jar. He said: “The Messenger of Allah [SAW] forbade it.' I got upset when I heard that, so I went to Ibn 'Abbas and said: “Ibn 'Umar was asked about something, and I found it difficult.' He said: “What was it?' I said: “He was asked about Nabidh made in an earthenware jar.' He said: “He spoke the truth; the Messenger of Allah [SAW] forbade it.' I said: “What is an earthenware jar?' He said: “Anything that is made of clay”””””””"
