Maliks Muwatta Book 042, Hadith Number 008.

Section : Mixtures of Fruit Disapproved for Making Nabidh.

Yahya related to me from Malik from a reliable source from Bukayr ibn Abdullah ibn al-Ashajj from Abd ar-Rahman ibn al-Hubab al-Ansari from Abu Qatada al-Ansari that the Messenger of Allah, may Allah bless him and grant him peace, forbade making nabidh from dates and raisins together, and nearly ripe dates and fresh dates together.

Malik said, "That is the way of doing things among us in which the people of knowledge in our city continue. It is disapproved of because the Messenger of Allah, may Allah bless him and grant him peace, forbade it."
