Heart Transplant – Pig's Heart
There’s already scientific evidence available that diet affects DNA sequencing of the genes. As Ghamidi sahab alluded to in the video, there’s also an inevitable psychological affect that can’t be ignored. The hadith you shared is not really relevant to this matter because it’s about a temporary oral remedy as opposed to permanently making something a part of your body. The key thing to understand is the illat or the fundamental reason why the flesh of swine has been made haram . Since the procedure of pig heart transplant has the same illat , in Ghamidi sahab’s opinion such a transplant can’t be deemed permissible. The rest of your concerns have already been addressed in the video, which I’m sharing here again for your review: https://www.youtube.com/watch?v=zOhd1ioIKLc
