حَدَّثَنِي يَحْيَى، عَنْ مَالِكٍ، عَنْ نَافِعٍ، عَنْ عَبْدِ اللَّهِ بْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم خَطَبَ النَّاسَ فِي بَعْضِ مَغَازِيهِ - قَالَ عَبْدُ اللَّهِ بْنُ عُمَرَ - فَأَقْبَلْتُ نَحْوَهُ فَانْصَرَفَ قَبْلَ أَنْ أَبْلُغَهُ فَسَأَلْتُ مَاذَا قَالَ فَقِيلَ لِي نَهَى أَنْ يُنْبَذَ فِي الدُّبَّاءِ وَالْمُزَفَّتِ ‏.‏

Yahya related to me from Malik from Nafi from Abdullah ibn Umarthat the Messenger of Allah, may Allah bless him and grant him peace,addressed the people in one of his raids. Abdullah ibn Umar said, "Iwent towards him, but he finished before I reached him. I asked aboutwhat he had said. Someone said to me, 'He forbade preparing nabidh ina gourd or in a jug smeared with pitch.'" Translation Not Available
