Muwatta Imam Malik Book of Drinks, Hadith 6
Yahya related to me from Malik from al-Ala ibn Abd ar-Rahman ibn Yaqub from his father from Abu Hurayra that the Messenger of Allah ﷺ forbade preparing nabidh in a gourd or in a jug smeared with pitch.
وَحَدَّثَنِي عَنْ مَالِكٍ، عَنِ الْعَلاَءِ بْنِ عَبْدِ الرَّحْمَنِ بْنِ يَعْقُوبَ، عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ ﷺ نَهَى أَنْ يُنْبَذَ فِي الدُّبَّاءِ وَالْمُزَفَّتِ .
