The Prophet (may Allah's peace and blessings be upon him) used to say before entering the bathroom: "Allāhumma inni a‘ūdhu bika min al-khubuth wa al-khabā’ith (O Allah, I seek refuge in You from the male and female devils)

Whenever the Prophet (may Allah's peace and blessings be upon him) wanted to enter the place where he would relieve himself, either urinating or defecating, he would seek refuge with Allah and resort to Him to protect him from the evil of the male and female devils. The "Khubuth" and "Khabā’ith" were also said to mean evil and impurities.
