Sahih Muslim Book 7, Hadith Number 2723.

Chapter : Which animal the Muhrim and the non-Muhrim are permitted to kill in the state of Ihram at the conclusion of it (within the precincts of the Ka’ba).

I’Aisha (Allah be pleased with her) reported Allah’s Messenger (may peace be upon him) as saying: Five are the beasts 1618 harmful and vicious and these must be killed even within the precincts of the Ka’ba: crow, kite, voracious dog, scorpion and rat.
