Although alcoholic drinks are prohibited for consumption, alcohol derived from
grapes, dates, and raisins is also considered najis or unclean. Use of alcohol from
these sources is not allowed even for nonfood uses, such as in cosmetics, perfumes,
and personal care products. So alcohol is mainly haram as a food or unclean for
other uses if it is from traditional sources of grapes and dates. Alcohol if made
from halal sources can be converted into halal products. In contrast, pork is from
pig, a haram source, and all products and ingredients derived from pork remain
haram.
