question #3 Sahih Muslim 1199a, Book 15, Hadith 78 : How does Islamic law address the issue of killing certain animals during the pilgrimage?

Five are the (beasts) which if one kills them in the precincts of the Ka’ba or in the state of lhram entail no sin: rat, scorpion, crow, kite and voracious dog. In another version the words are:” as a Muhrim and in the state of lhram”.
