Is it permissible to deal with and buy from government institutions that sell various goods, including alcoholic beverages in a separate section, knowing that their prices are much lower than the market, especially for those with limited income?

Allah has forbidden the manufacturing, selling, and purchasing of alcohol, even for non-Muslims. It is authentically reported from the Prophet, peace and blessings be upon him, that he said: "Indeed, Allah and His Messenger have forbidden the sale of alcohol, dead animals, pigs, and idols." It is not permissible to trade in what Allah has forbidden, even with disbelievers, because the Prophet, peace and blessings be upon him, said: "Indeed, when Allah forbids a thing, He forbids its price." And (He cursed alcohol, its drinker, its seller, its buyer, its carrier, the one to whom it is carried, the one who consumes its price, its presser, and the one for whom it is pressed). As for buying other goods from someone who sells alcohol, there is no harm in that, due to His Almighty saying: "And Allah has permitted trade."
