Verily during his illness the prophet recited "al-Mu'awwadhatayn" [Sura 113, and 114], and blow his breath upon his body while rubbing his face. [This was done in an effort to be healed].

Aisha, the wife of the prophet used to say, "When the apostle of Allah fell ill, Gabriel chanted on him saying, "In the name of Allah Who will cure you and Who will heal you from every malady (and will ward off) the evil of envier who envies and from smite of the evil eye.""

Verily, whenever the apostle of Allah fell ill, he asked for recovery, from Allah. But in the illness as a result of which he died, he did not pray for recovery; he used to say, "O soul! What has happened to thee that thou are seeking refuge in every place of refuge?"
