(6802) The Chapter of (the punishement for) those who wage war (against Allah and His Messenger) from the people who are disbelievers and from those who have turned renegades (converted from Islam). And the Statement of Allah: The recompense of those who wage war against Allah and His Messenger, and do mischief in the land is only that they shall be killed or crucified, or their hands and their feet be cut off on the opppsite sides, or be exiled from the land... (V.5:33)
Narrated Anas: Some people from the tribe of `Ukl came to the Prophet and embraced Islam. The climate of Medina did not suit them, so the Prophet ordered them to go to the (herd of milch) camels of charity and to drink, their milk and urine (as a medicine). They did so, and after they had recovered from their ailment (became healthy) they turned renegades (reverted from Islam) and killed the shepherd of the camels and took the camels away. The Prophet sent (some people) in their pursuit and so they were (caught and) brought, and the Prophets ordered that their hands and legs should be cut off and that their eyes should be branded with heated pieces of iron, and that their cut hands and legs should not be cauterized, till they die.
