Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: I heard Sayyiduna Umar (may Allah be pleased with him) saying this from the pulpit of the Prophet (peace and blessings be upon him): "To proceed, O people! When the command regarding the prohibition of alcohol was revealed, it was being made from five things: grapes, dates, honey, wheat, and barley. As for khamr (intoxicant), it is every substance that covers the mind. O people! There are three things about which I wished that the Prophet (peace and blessings be upon him) had explained to us in more detail before he departed from us: kalalah (the issue of inheritance when there are no parents or children), the issue of the grandfather (in inheritance), and some forms of usury."
