بِسْمِ اللَّهِ اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ الْخُبُثِ وَالْخَبَائِثِ
Bismillah. Allahumma inni a'udhu bika minal-khubthi wal-khaba'ith
In the Name of Allah. O Allah, I seek refuge in You from evil male and female jinn.
The Prophet ﷺ taught this to be said before entering the bathroom. Al-Khubthi and Al-Khaba'ith refer to male and female jinn (or evil and wicked things). The bathroom is a place where jinn are present, so seeking Allah's protection is especially important.
