Abu Hadir said:

Ibn 'Umar was asked about earthenware jars: can nabeedh be made in them? He said: The Messenger of Allah (ﷺ) forbade that. The man went to Ibn "Abbas and told him what Ibn 'Umar had said. Ibn 'Abbas said: He was right. The man said to Ibn ‘Abbas: What kind of earthenware jar did the Messenger of Allah (ﷺ) forbid? He said. That which is made from clay.
