Maliks Muwatta Book 24, Hadith Number 5.

Section : Methods of Slaughter Permitted in Necessity.

Yahya related to me from Malik from Thawr ibn Zayd ad-Dili that Abdullah ibn Abbas was asked about animals slaughtered by the Christian Arabs. He said, “There is no harm in them,” but he recited this ayat, “Whoever takes them as friends is from them.” (Sura 5 ayat 54).
