The Book Pertaining to Paradise, Its Description, Its Bounties and Its Intimates (Kitab Al-Jannat wa Sifat Na'imiha wa Ahliha)
Muslim :: Book 40 : Hadith 6839
Sa'id b. Musayyib explained" al-bahira" as that animal which is not milked but for the idols. and none amongst the people milks them, and" as-sa'iba" as that animal which is let loose for the deities. Nothing is loaded over it, and Ibn Musayyib narrated that Abu Huraira stated that Allah's Messenger (may peace be upon him) said: I saw 'Amr b. 'Amir al-Khuzili dragging his intestines in fire and he was the first who devoted animals to deity.
