Sayyiduna Shurahbil (may Allah be pleased with him) said: We were sitting with the Prophet (peace and blessings be upon him) when a tall, fair-skinned Bedouin came to him (peace and blessings be upon him) and said: O Messenger of Allah! There is an old man who has a raging fever that will make him visit the graves. The Messenger of Allah (peace and blessings be upon him) said: "An old man who has a raging fever; it is an expiation and a purification for him." The man repeated his words, and the Prophet (peace and blessings be upon him) also repeated his, three or four times. Then the Prophet (peace and blessings be upon him) said: "Since you refuse, then it is as you say, and whatever Allah has decreed will come to pass." The narrator said: By the evening of the next day he had died.
