Pilgrimmage (Hajj)

Bukhari :: Book 2 :: Volume 26 :: Hadith 657

Narrated Ibn Abbas:

On the Day of the Conquest of Mecca, Allah's Apostle said, "Allah has made this town a sanctuary. Its thorny bushes should not be cut, its game should not be chased, and its fallen things should not be picked up except by one who would announce it publicly."
