It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Prophet (peace and blessings be upon him) said: Whoever drinks alcohol, flog him. If he drinks again, then flog him again. If he drinks a third time, then flog him again. And on the fourth or fifth occasion, he said: Then kill him.
