Supplication Entering the Bathroom
اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ الْخُبُثِ وَالْخَبَائِثِ
allahumma inni a'udhu bika minal-khubuthi wal-khaba'ith
O Allah, I seek refuge in You from the evil and the wicked.
Source: HR. al-Bukhari and Muslim
This supplication acts as a barrier between a servant's private parts and the jinn when entering the bathroom.
