Narrated Abu Musa:
that when Allah's Apostle sent him and Mu'adh bin Jabal to Yemen, he said to them, "Facilitate things for the people (treat the people in the most agreeable way), and do not make things difficult for them, and give them glad tidings, and let them not have aversion (i.e. to make the people hate good deeds) and you should both work in cooperation and mutual understanding, obey each other." Abu Musa said, "O Allah's Apostle! We are in a land in which a drink named Al Bit' is prepared from honey, and another drink named Al-Mizr is prepared from barley." On that, Allah's Apostle said, "All intoxicants (i.e. all alcoholic drinks) are prohibited."
