Musnad Abu Ya'la al-Mawsili 113:26

Abu Bakr narrated to us, Isma'il bin 'Ulayyah narrated to us, from Hajjaj bin Abi 'Uthman, Abu Raja' the freed slave of Abu Qilabah narrated to me, from Abu Qilabah, he said: Anas bin Malik narrated to me that a group of eight men from 'Ukl came to the Messenger of Allah (ﷺ) and pledged allegiance to him upon Islam. They found the land unhealthy and their bodies became ill, so they complained of that to the Messenger of Allah (ﷺ). He said: "Will you not go out with our shepherd with his camels, and consume from their urine and their milk?" So they recovered, then they killed the shepherd and drove off the camels. That reached the Messenger of Allah (ﷺ), so he sent [men] in their tracks. They were overtaken and brought back. He ordered regarding them, so their hands and feet were cut off, and their eyes were branded with hot irons, then they were cast out in the sun until they died.
