It was narrated that Zaid bin Arqam said: “The Messenger of Allah ﷺ said: ‘These Hushush (waste areas) are visited (by devils), so when anyone of you enters, let him say: ‘Allahumma inni a’udhu bika minal-khubthi wa’lkhaba”ith (O Allâh, I seek refuge with You from male and female devils).” (Sahih) Other chains with similar wording.
