With these two sūrahs one seeks refuge in Allah from every kind of evil (sharr), and they may be recited for any circumstance in which one fears harm. They serve to remind the believer to put his trust in Allah and depend upon Him alone. Sūrah al-Falaq mentions external evils which threaten mankind, such as what occurs in the darkness of night, the plots of magicians and the harms caused by those who envy and harbor jealousy. And Sūrah an-Nās deals with internal evil which is found within the self, such as the suggestions of the Shayṭān and corrupt inclinations of the soul.
