Sahih Al Bukhari Hadith Number 1501

Narrated Anas: Some people from `Uraina tribe came to Medina and its climate did not suit them, so Allah’s Messenger (peace eb upon him) (peace be upon him) allowed them to go to the herd of camels (given as Zakat) and they drank their milk and urine (as medicine) but they killed the shepherd and drove away all the camels. So Allah’s Messenger (peace be upon him) sent (men) in their pursuit to catch them, and they were brought, and he had their hands and feet cut, and their eyes were branded with heated pieces of iron and they were left in the Harra (a stony place at Medina) biting the stones. (See Hadith No. 234, Vol. 1)
