Is it permissible to work in an establishment that produces glass bottles sometimes used as containers for alcoholic beverages?

If your work in manufacturing bottles is specifically for alcoholic beverages, then it is forbidden, due to the hadith of Ibn Umar that the Prophet, peace and blessings be upon him, said: "Allah has cursed wine, its drinker, its server, its seller, its buyer, its presser, the one for whom it is pressed, its carrier, and the one to whom it is carried." However, if the bottles are used for wine and for other purposes, then there is no harm in your work.
