>>13352546Narrated Ibn 'Abbas: That the Messenger of Allah said: "Whomever you see having relations with an animal then kill him and kill animal." So it was said to Ibn 'Abbas: "What is the case of the animal?" He said: "I did not hear anything from the Messenger of Allah about this, but I see that the Messenger of Allah disliked eating its meat or using it, due to the fact that such a (heinous) thing has been done with that animal."
