"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)
«حَرَّمَهُ رَسُولُ اللهِ ﷺ» فَشَقَّ عَلَيَّ لَمَّا سَمِعْتُهُ فَأَتَيْتُ ابْنَ عَبَّاسٍ فَقُلْتُ إِنَّ ابْنَ عُمَرَ سُئِلَ عَنْ شَيْءٍ فَجَعَلْتُ أُعَظِّمُهُ قَالَ مَا هُوَ؟ قُلْتُ سُئِلَ عَنْ نَبِيذِ الْجَرِّ فَقَالَ «حَرَّمَهُ رَسُولُ اللهِ ﷺ» فَقَالَ صَدَقَ «حَرَّمَهُ رَسُولُ اللهِ ﷺ» فَقُلْتُ وَمَا الْجَرُّ؟ قَالَ كُلُّ شَيْءٍ يُصْنَعُ مِنْ مَدَرٍ
