Sahih al-Bukhari Book 86, Hadith 33
A group of people from `Ukl (tribe) came to the Prophet (ﷺ) 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 Messenger (ﷺ)!
Provide us with milk." The Prophet (ﷺ) 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.")
The Prophet (ﷺ) cut off the hands and feet of the men belonging to the tribe of `Uraina and did not cauterise (their bleeding limbs) till they died.
A group of people from `Ukl (or `Uraina) tribe ----but I think he said that they were from `Ukl came to Medina and (they became ill, so) the Prophet (ﷺ) ordered them to go to the herd of (Milch) she-camels and told them to go out and drink the camels' urine and milk (as a medicine). So they went and drank it, and when they became healthy, they killed the shepherd and drove away the camels. This news reached the Prophet (ﷺ) early in the morning, so he sent (some) men in their pursuit and they were captured and brought to the Prophet (ﷺ) before midday. He ordered to cut off their hands and legs and their eyes to be branded with heated iron pieces and they were thrown at Al-Harra, and when they asked for water to drink, they were not given water. (Abu Qilaba said, "Those were the people who committed theft and murder and reverted to disbelief after being believers (Muslims), and fought against Allah and His Apostle").
