Musnad Ahmad 30:2231

'Affan narrated to us, he said: Yazid bin Ibrahim narrated to us, he said: Muhammad—meaning Ibn Sirin—narrated to us, he said: Abu Hurairah and 'Abdullah bin 'Umar narrated to me. As for one of them, he attributed it to the Prophet (may Allah bless him and grant him peace), and as for the other, he attributed it to 'Umar. One of them said: "He forbade the skins, the pitch-coated vessels, the gourds, and the green jars." The other said: "He forbade the skins, the pitch-coated vessels, the gourds, and the glazed jars or pottery"—Muhammad was in doubt—"and the green jars."
