Maliks Muwatta Book 42, Hadith Number 10.

Section : Wine Made Haram.

Yahya related to me from Malik from Zayd ibn Aslam from Ata ibn Yasar that the Messenger of Allah, may Allah bless him and grant him peace, was asked about al-Ghubayra. He said, “There is no good in it,” and forbade it. Malik said, “I asked Zayd ibn Aslam, ‘What is al-Ghubayra?’ He said, ‘It is an intoxicant.'”
