Sahih al-Bukhari Book 86, Hadith 35
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."
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").
The Prophet (ﷺ) said, "Whoever guarantees me (the chastity of) what is between his legs (i.e. his private parts), and what is between his jaws (i.e., his tongue), I guarantee him Paradise."
