Sahih Muslim | Book 16 | Hadith Number 4132

Narrated by Anas b. Malik
Anas b. Malik reported that some people of the tribe of 'Ukl or 'Uraina came to Allah's Messenger (may peace be upon him), and they found the climate of Medina uncongenial. Allah's Messenger (may peace be upon him) commanded them to the milch she-camels and commanded them to drink their urine and their milk. The rest of the hadith is the same (and the concluding words are): "Their eyes were pierced, and they were thrown on the stony ground. They were asking for water, but they were not given water.
