`UKL

Muhammad and some people of `Ukl Some people came and fell sick. Muhammad gave them permission to use the camels milk and urine as medicine and they became well. After that, they killed the shepherd and killed the camels, and after being caught, Muhammad had them tortured till they died.
Narrated Anas:
A group of people from 'Ukl (tribe) came to the Prophet and they were living with the people of As-Suffa, but they became ill as the climate of Medina did not suit them, so they said, "O Allah's Apostle! Provide us with milk." The Prophet said, I see no other way for you than to use the camels of Allah's Apostle." So they went and drank the milk and urine of the camels, (as medicine) and became healthy and fat. Then they killed the shepherd and took the camels away. When a help-seeker came to Allah's Apostle, he sent some men in their pursuit, and they were captured and brought before mid day. The Prophet ordered for some iron pieces to be made red hot, and their eyes were branded with them and their hands and feet were cut off and were not cauterized. Then they were put at a place called Al-Harra, and when they asked for water to drink they were not given till they died. (Abu Qilaba said, "Those people committed theft and murder and fought against Allah and His Apostle.") (Sahih Bukhari 8.796, also Sahih Bukhari 8.794, Sahih Bukhari 8.795, Sahih Bukhari 8.797)
