Sayyiduna al-Sa'ib bin Yazid (may Allah be pleased with him) said: In the time of the Prophet (peace and blessings be upon him), of Sayyiduna Abu Bakr (may Allah be pleased with him) and in some of the early time of Sayyiduna Umar (may Allah be pleased with him), we did not flog for wine, until people went to excess in it. Then Sayyiduna Umar (may Allah be pleased with him) flogged with eighty lashes, but still they did not desist, so Sayyiduna Umar (may Allah be pleased with him) kept the punishment fixed at eighty lashes and said: When a man is intoxicated, he makes false accusations against people and utters slander.
