In the Holy Book - Koran

(They ask thee what is Lawful to them (as food). Say: Lawful unto you Are (all) things good and pure: And what ye have taught Your trained hunting animals (To catch) in the manner Directed to you by Allah : Eat what they catch for you, But pronounce the name of Allah over it : and fear Allah; for Allah is swift In taking account.).

(Thou wouldst have deemed them Awake, while they were asleep, And We turned them On their right and on Their left sides: their dog Stretching forth his two forelegs On the threshold: If thou Hadst come up on to them, Thou wouldst have certainly Turned back from them in flight, And wouldst certainly have been Filled with terror of them.)
