What is the ruling on medicines that contain a small percentage of alcohol?

The Shaykh : The questioner says: There are some medicines that contain some alcohol in their composition, to the extent that it is known by its smell and taste, knowing that the dose of the medicine is not mentioned. It is established from the Prophet (peace and blessings be upon him) that he said: “What intoxicates in large quantity, its small quantity is forbidden.” The meaning is: if the drink, if you increase it, you become intoxicated, and if you decrease it, you do not become intoxicated, then it is forbidden. The criterion is the drink itself, not the drinker, because some of the drinkers who are addicted to alcohol may drink a lot and not become intoxicated because they are accustomed to it, but the Messenger (peace and blessings be upon him) considered the drink, not the drinker. So if the drink, if its large quantity intoxicates, then its small quantity also intoxicates. What intoxicates is the *firqa*, and the *firqa* is a measure that holds sixteen *sa'*s, so a handful of it is forbidden. And this is a point where some students err in understanding it.
Because they think that the meaning of the saying of the Messenger (peace and blessings be upon him), “What intoxicates in large quantity, its small quantity is forbidden,” is that whatever is mixed with a little alcohol is forbidden. And that is not the case. Rather, if something is mixed with alcohol, and this mixture or this admixture does not affect the thing it is mixed with, then it has no effect and no ruling. So if, for example, these medicines contain a percentage of alcohol, but it does not show any effect in intoxication, then these medicines are not forbidden merely because they contain a mixture of alcohol. Because the impure thing or the forbidden thing, if it is mixed with the pure or the permissible and its effect does not appear, then the ruling is for the pure or the permissible. And we give you an example: if a drop of urine, but it was not confirmed...
