Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: He heard Sayyiduna Umar (may Allah be pleased with him) saying this from the pulpit of the Prophet (peace and blessings of Allah be upon him): "To proceed! O people, when the command of the prohibition of alcohol was revealed, it was made from five things: grapes, dates, honey, wheat, and barley. And in general, khamr (intoxicant) is called every such thing that covers the intellect."
