Sayyiduna Anas bin Malik (may Allah be pleased with him) says that people of the tribe of Uraynah came to the Messenger of Allah (peace and blessings be upon him). The climate did not suit them, so the Messenger of Allah (peace and blessings be upon him) said: "If you wish, drink the milk and urine of the camels of charity." They did so and recovered. Then they killed the herdsmen, apostatised, and also took away the camels of the Messenger of Allah (peace and blessings be upon him). When the Prophet (peace and blessings be upon him) learned of it, he had them pursued; when they were captured and brought, he (peace and blessings be upon him) had their hands and feet cut off, had hot iron rods passed over their eyes, and left them on the stony ground until they died.
(b) Abd al-Wahhab narrates from Humayd (that he said): I do not remember whether "drink their urine" is mentioned or not.
