Zadan said: "I asked 'Abdullah bin 'Umar: 'Tell me of something that you heard from the Messenger of Allah [SAW] concerning vessels and explain it.' He said: 'The Messenger of Allah [SAW] forbade Al-Hantam, which are what you call earthenware jars. And he forbade Ad-Dubba' which are what you call squash. And he forbade An-Naqir, which are hollowed-out date palm wood. And he forbade Al-Muzaffat which are (Al-Muqayyar) vessels daubed with tar.'"
