Zadhan (may Allah have mercy on him) said: I asked Sayyiduna Ibn Umar (may Allah be pleased with them both): Tell us about the vessels which the Prophet (peace and blessings be upon him) forbade; tell us in your language and then explain it to us in our language. He said: "He forbade earthenware jars, pitch-coated jars, gourd vessels and jars made by hollowing out the root of a date palm, and he ordered that nabidh be made in water-skins."
