Is gelatin made from pig bones in the United States forbidden, considering that the Quranic verse specified "flesh of swine" and not "swine" as a whole? And is it permissible for a pregnant woman who does not fast to pay Zakat instead of giving a specified amount (fidyah) to ensure it is not missed, especially if she will breastfeed for two years?

If this material is made from pig bones, then it is undoubtedly forbidden (haram (definition)), because pig bone and meat are the same in terms of prohibition. The jurists have unanimously agreed on the prohibition of using pig bone due to its impurity. And the Almighty’s saying: "Or there be carrion, or blood poured forth, or flesh of swine—for that is an abomination" indicates the prohibition of the essence of the pig and all its parts. The pronoun "for that is an abomination" refers to the entire pig, not just its meat, which forbids all its parts as a precaution.
