It was narrated that Ibn 'Umar said: "The Messenger of Allah (ﷺ) [SAW] delivered a Khutbah and quoted the Verse about Khamr. A man said: 'O Messenger of Allah, what do you think about Al-Mizr (beer)?' He said: 'What is beer?' He said: 'A (drink) from grains that is made in Yemen.' He said: 'Does it intoxicate?' He said: 'Yes.' He said: 'Every intoxicant is unlawful.'"
