Narrated Ibn Umar:
I heard 'Umar while he was on the pulpit of the Prophet saying, "Now then O people! The revelation about the prohibition of alcoholic drinks was revealed; and alcoholic drinks are extracted from five things: Grapes, dates, honey, wheat and barley. And the alcoholic drink is that which confuses and stupefies the mind."
