Sayyiduna Abu Musa (may Allah be pleased with him) says: The Prophet (peace and blessings be upon him) sent me and Mu'adh to Yemen and said: "Go, and call the people to Islam; make things easy and do not make them difficult; give glad tidings and do not drive people away." I said: O Messenger of Allah, give us a ruling about two drinks we used to make in Yemen: al-bit' from honey, which we steep until it becomes strong, and al-mizr from wheat, barley and corn, which we steep until it becomes strong. He said: The Prophet (peace and blessings be upon him) had been given comprehensive words and their conclusions, and he said: "I forbid every intoxicant that keeps one from prayer." He said: Then we set off.
