Those privies are attended by the devils, so if anyone of you goes to a privy, let him say: I seek refuge with Allah from the male and female devils

The place where one relieves himself (privy) is attended by the Jinn and the devils who wait there to inflict harm and trouble on humans. A privy is a place where one's private parts are uncovered, and the name of Allah is not mentioned. So, when a Muslim goes there, he should say this supplication: I seek refuge with Allah from the males and females from among the devils.
