From Sahih Muslim (Hadith 4355):
Anas b. Malik reported that some people of the tribe of 'Ukl or 'Uraina came to Allah's Messenger (ﷺ), and they found the climate of Medina uncogenial. Allah's Messenger (ﷺ) 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
