What is the ruling on dealing with a husband who drinks intoxicants daily, yet shows no symptoms of intoxication or loss of reason, and rejects its prohibition under the pretext that the prohibition is specific to those who lose their minds and act criminally, knowing that he wishes to quit but returns to it?

Alcohol is forbidden by the Qur'an, Sunnah, and scholarly consensus. The reason for its prohibition is its intoxicating effect, for "every intoxicant is khamr, and every intoxicant is forbidden." This applies even if the drinker does not become intoxicated, because the consideration is whether the drink is capable of causing intoxication. "That which intoxicates in large quantities, a small quantity of it is forbidden." The drinker's immunity to its intoxicating effect does not lift the prohibition. The alcohol drinker must repent and abstain from it, and seek treatment if necessary. The wife should advise him and turn to Allah in prayer for his guidance.
