From Sahih Bukhari (Hadith 4619):
Narrated Ibn `Umar:I heard `Umar while he was on the pulpit of the Prophet (ﷺ) 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
