Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates that Sayyiduna Umar (may Allah be pleased with him) delivered a sermon to us on the pulpit of the Messenger of Allah (peace and blessings be upon him), praised Allah, and after giving advice and admonition, said: "To proceed! On the day when the command regarding the prohibition of wine was revealed, it was being made from five things: grapes, dates, wheat, barley, and honey. And khamr (wine) refers to anything that covers (removes) the intellect."
