Boiled Grape Juice
Issue No. 126- If grape juice ferments by itself (the sort of fermentation, which is usually the preliminary stage of becoming an alcoholic beverage), it will be najis and haram. However, if it is fermented by fire or something else, it is not najis, but haram to drink, and the same ruling applies to the juice of dates, currants and raisins as an obligatory precaution.
