It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings of Allah be upon him) went to visit a Bedouin who was ill. The Prophet (peace be upon him) said: "There is no harm and no fear for you; this illness is a means of purification from sins, if Allah wills." The narrator says that the Bedouin replied: "No, rather it is a fever that is boiling in an old man so that it may take him to the graveyard." The Prophet (peace be upon him) said: "Then it will be as you say."
