"Anas b. Malik reported that some people belonging (to the tribe) of 'Uraina came to Allah's Messenger (may peace be upon him) at Medina, but they found its climate uncongenial. So Allah's Messenger (may peace be upon him) said to them: If you so like, you may go to the camels of Sadaqa and drink their milk and urine. They did so and were all right."
