I asked the Messenger of Allah (ﷺ) about the hyena. He replied: It is game, and if one who is wearing ihram (pilgrim's robe) hunts it, he should give a sheep as atonement.
Sunan Abi Dawud Book 28, Hadith 66
← Previous Hadith The people of pre-Islamic times used to eat some things and leave others alone, considering them unclean. Then Allah sent His Prophet (ﷺ) and sent down His Book, marking some things lawful and others unlawful; so what He made lawful is lawful, what he made unlawful is unlawful, and what he said nothing about is allowable. And he recited: "Say: I find not in the message received by me by inspiration any (meat) forbidden to be eaten by one who wishes to eat it...." up to the end of the verse.

Sunan Abi Dawud Book 28, Hadith 65 Next Hadith → The Messenger of Allah (ﷺ) prohibited eating fanged beasts of prey.
