Ibn ‘Abbas said that the Prophet went in to visit a Bedouin Arab, and when he entered to visit a sick man he was accustomed to say,“No harm will come; it is a purification, if God will.”He repeated these words, and when the man replied,“Not at all; it is on the contrary a fever which is boiling in an old man and will cause him to visit the graves,”the Prophet said,“Very well, then.”Bukharl transmitted it.
