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.' "
