سنن أبي داود

Narrated Ibn 'Abbas: The verse: "So eat of (meats) on which Allah's name hath been pronounced" and the verse: "Eat not of (meats) on which Allah's name hath not been pronounced" were abrogated, meaning an exception was made therein by the verse: "The food of the people of the Book is lawful unto you and yours is lawful unto them."
