The flesh and skin of animals whose meat is unlawful to eat – except those mentioned in the previous ruling (masʾalah) – become pure if they are slaughtered or killed by hunting with a weapon, whether the animal is a predatory one or not. This applies even to elephants, bears, and apes (about which there is a difference of opinion from a jurisprudential perspective).
However, if animals whose meat cannot be eaten are killed by hunting dogs, then to consider them pure is problematic (maḥall al‑ishkāl) [i.e. based on obligatory precaution (al‑iḥtiyāṭ al‑wājib), they are not considered pure].[1]
