Muwatta Malik, Book 42, Hadith 1549 (In-Book)

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.' "

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ زَيْدِ بْنِ أَسْلَمَ، عَنْ عَطَاءِ بْنِ يَسَارٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم سُئِلَ عَنِ الْغُبَيْرَاءِ فَقَالَ ‏ "‏ لاَ خَيْرَ فِيهَا ‏" ‏ ‏.‏ وَنَهَى عَنْهَا ‏.‏ قَالَ مَالِكٌ فَسَأَلْتُ زَيْدَ بْنَ أَسْلَمَ مَا الْغُبَيْرَاءُ فَقَالَ هِيَ الأُسْكَرْكَةُ ‏.‏
