Transliteration: ALLAHUMMA INNI A’AOZU BIKA MINAL KHUBZI WA’AL KHABAIS
Translation: O ALLAH, I seek refuge in you from Al-Khubth and Al-Khabaa’ith

People use the bathroom many times during the day and night. If they observe these Sunan for entering and leaving every time they go, they will fulfill two Sunan for entering and two Sunan for leaving.
Al-Khubth and Al-Khabaa’ith – These are male and female devils. In order to be protected by ALLAH from their evil, one should seek refuge from them when entering the toilet or washroom. The toilet is one of their places of abode.
