It is narrated from Sayyiduna Jabir (may Allah be pleased with him) that it was said in the presence of the Prophet (peace and blessings be upon him): "The fever has utterly exhausted us and will not leave us." So he (peace and blessings be upon him) said: "If you wish that it (this affliction) be lifted from you, it will be removed; and if you wish that it be a means of purification (from sins) for you, it will remain." The Companions (may Allah be pleased with them) said: "(O Messenger of Allah (peace and blessings be upon him)!) Let it remain a means of purification for us."
