It is narrated from Sayyiduna Ibn Amr (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever drinks alcohol, flog him. If he drinks again, flog him again. And if he drinks a fourth time, then kill him." On this basis, Sayyiduna Abdullah bin Amr (may Allah be pleased with him) used to say: "Bring to me a person who has drunk alcohol a fourth time; it is obligatory upon me to kill him."
