Ibn ‘Abbas reported God’s Messenger as saying, “If anyone has sexual intercourse with an animal, kill him and kill it along with him.” Ibn ‘Abbas was asked what offence could be attributed to the animal and replied, “I did not hear anything about that from God’s Messenger, but I think he disapproved of its flesh being eaten or of any use being made of it when such a thing had been done to it.” Tirmidhi, Abu Dawud and Ibn Majah transmitted it.
