Anas told that some people of ‘Ukl who had come to the Prophet (ﷺ) and accepted Islam found Medina unhealthy, so he ordered them to go to the camels of the sadaqa and drink some of their urine and their milk. They did so and became well, after which they apostatised, killed the herdsmen and drove off the camels. So he sent people in pursuit of them, and when they were brought he had their hands and feet cut off and their eyes put out and left them to die without cauterising them to stop the flow of blood. A version says nails were driven into their eyes. Another says he ordered nails to be heated and after having them blinded with them he had them thrown out on the harra, and although they begged for water they were left to die without being given any. (Bukhari and Muslim.)
