The Sun have today uncovered instances where Muslims visiting people in hospital would not wash their hands on entry to wards because the handgel provided contains alcohol.
It would have been a good idea for the Sun to actually ask some Islamic scholars for some rulings on the matter. It is forbidden to consume alcohol, but there is no such prohibition on its external use.
This goes back to reasoning. Any course of action which would lead to the mind being impaired in intoxication is considered haraam. This is why drinking alcoholic beverages is prohibited, but even if you had to consume the soap, it would leave you ill yes, drunk no.
Normally you would take what the Sun says with a pinch of salt. However, I can believe this one as this kind of petty misguided scrupulousness is present amongst all too many Muslims. Ignorance would be putting it mildly when we come to an issue where rather that look at what their faith actually says, they would risk spreading vicious hospital bugs.
Islam favours community benefit, making this an especially sad story. For more info, see this fatwa about the external use of perfumes (not even something with a health benefit) containing alcohol.
