What did Allah's Messenger (peace be upon him) say about the five vicious animals?
 Hafsa, the wife of Allah's Apostle (may peace be upon him), reported Allah's Messenger (may peace be upon him) having said this:                      There are five beasts, all of them are vicious and harmful and there is no tin for one who kills them (and these are): scorpion, crow. kite, rat and voracious dog.
