Maliks Muwatta Book 25, Hadith Number 14.
Section : Prohibition Against Eating Animals with Fangs.
Yahya related to me from Malik from Ismail ibn Abi Hakim from Abiyda ibn Sufyan al-Hadrami from Abu Hurayra that the Messenger of Allah, may Allah bless him and grant him peace, said, “Eating animals with fangs is haram.”
Malik said, “This is the custom among us.”
