Muwatta Malik, Book 42, Hadith 6 (USC-MSA)

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, may Allah bless him and grant him peace, 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 صلى الله عليه وسلم نَهَى أَنْ يُنْبَذَ فِي الدُّبَّاءِ وَالْمُزَفَّتِ ‏.‏
