"The Messenger of Allah [SAW] said: 'Khamr comes from these two.'" Suwaid (one of the narrators) said: "From these two trees: The date palm and the grapevine."
"I heard 'Umar, may Allah be pleased with him, delivering a Khutbah on the Minbar of Al-Madinah and he said: 'O people, on the day that the prohibition of Khamr was revealed, it was made from five things: From grapes, dates, honey, wheat and barley. Khamr is that which overcomes the mind.'"
