Sayyiduna Ibn Umar (may Allah be pleased with them both) says that the Prophet (peace and blessings be upon him) said: "Every intoxicant is wine, and every intoxicant is unlawful. Whoever drinks wine in this world and dies while habitually drinking it, not having repented from it, will not drink it in the Hereafter."
