Sahih al-Bukhari Book 86, Hadith 34
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").
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) said, "Seven (people) will be shaded by Allah by His Shade on the Day of Resurrection when there will be no shade except His Shade. (They will be), a just ruler, a young man who has been brought up in the worship of Allah, a man who remembers Allah in seclusion and his eyes are then flooded with tears, a man whose heart is attached to mosques (offers his compulsory congregational prayers in the mosque), two men who love each other for Allah's Sake, a man who is called by a charming lady of noble birth to commit illegal sexual intercourse with her, and he says, 'I am afraid of Allah,' and (finally), a man who gives in charity so secretly that his left hand does not know what his right hand has given."
