What parts of a Halal animal are impermissible to eat?
According to the Hanafi School of Islamic law, seven things from a Halal and lawfully-slaughtered animal cannot be eaten. The first of these seven items has been emphatically forbidden by a decisive text of the Qur’an, hence it is unlawful (haram) to consume it; whereas consuming the other six items is considered prohibitively disliked (makruh tahrim), because there is no decisive text regarding their prohibition although their prohibitive dislike is proven through non decisive texts. (See: Bada’i al-Sana’i 5/61)
