Musnad Ahmad 27:1045

Muhammad ibn Ja'far narrated to us, Shu'bah narrated to us, from 'Abd al-Khaliq, I heard Sa'id ibn al-Musayyib narrating from Ibn 'Umar: "That the Messenger of Allah (ﷺ) forbade the *duba'* (gourd), the *hantam* (green glazed jar), the *muzaffat* (pitch-coated vessel), and the *naqir* (hollowed-out log)." Sa'id said: "And the *muzaffat* was mentioned by someone other than Ibn 'Umar."
