Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates: I heard Sayyiduna Umar (may Allah be pleased with him) saying on the pulpit of the Prophet (peace and blessings be upon him): "To proceed! O people! When the command regarding the prohibition of wine was revealed, it was being made from five things: grapes, honey, dates, wheat, and barley. Every thing that covers the intellect (i.e., causes intoxication) is khamr (wine). O people! There are three things about which I wished that the Prophet (peace and blessings be upon him) had clarified for us: the share of the grandfather (in inheritance), kalalah (a person who dies leaving neither parents nor children), and some forms of usury."
