"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.'" (Using translation from Nasāʾī 5620)
عَنْ نَبِيذِ الْجَرِّ فَقَالَ حَرَّمَهُ رَسُولُ اللهِ ﷺ فَشَقَّ عَلَيَّ لَمَّا سَمِعْتُهُ فَأَتَيْتُ ابْنَ عَبَّاسٍ فَقُلْتُ إِنَّ ابْنَ عُمَرَ سُئِلَ عَنْ شَيْءٍ قَالَ فَجَعَلْتُ أُعَظِّمُهُ فَقَالَ وَمَا هُوَ؟ قُلْتُ سُئِلَ عَنْ نَبِيذِ الْجَرِّ فَقَالَ حَرَّمَهُ رَسُولُ اللهِ ﷺ فَقَالَ صَدَقَ حَرَّمَهُ رَسُولُ اللهِ ﷺ قُلْتُ وَمَا الْجَرُّ قَالَ كُلُّ شَيْءٍ صُنِعَ مِنْ مَدَرٍ
