Narrated Abdullah Ibn Abbas: The Apostle of Allah (peace be upon him) said: Every intoxicant is khamr and every intoxicant is forbidden.
The Prophet (peace be upon him) said: "Whatever intoxicates in large quantities, then a small quantity of it is forbidden."
Sheikh al-`Uthaymīn, while discussing these hadīth, says:
If a small quantity of alcohol is so submerged in something else that is has no tangible or theoretical effect, then the substance keeps the ruling that is in accordance with its own attributes. As for the hadīth that states 'Whatever intoxicates in large quantities, then a small quantity of it is forbidden', this refers to a certain beverage that intoxicates when someone drinks a lot of it but not when he drinks a little. It is unlawful to drink a small quantity of such a beverage, because even though a small quantity cannot make a person drunk, it can lead to drinking larger quantities." [Majmū` al-Fatāwā (4/260)]
