The Prophet (ﷺ) paid a visit to a sick bedouin. The Prophet (ﷺ) when visiting a patient used to say, "No harm will befall on you if Allâh will, it will be an expiation (for your sins)." So the Prophet (ﷺ) said to the bedouin, No harm will befall on you if Allâh will, it will be an expiation (for your sins)." The bedouin said, "You say an expiation? No, it is but a fever that is boiling or harassing an old man, and will lead him to the grave." " The Prophet (ﷺ) said, "Yes, then may it be as you say." [4:813-O.B]
