Here is a fact recounted from the Koran:

Hadith Sahid - story of Anas: people from the Ukl tribe came to the Prophet and embraced Islam ... they became apostolates ... and the Prophet ordered that their hands and feet be cut off, that their eyes be burned with iron spikes and that their mutilations should not be cauterized to cause death ... they were put in a place called Al Harra and when they asked for water, they did not receive it until their death.
