Anas said, "Some people of 'Ukl or 'Uraina tribe came to Medina and its climate did not suit them. So the Prophet ordered them to go to the herd of (Milch) camels and to drink their milk and urine (as a medicine). So they went as directed and after they became healthy, they killed the shepherd of the Prophet and drove away all the camels.
