1. Dua Before Entering the Toilet
Bukhari & Muslimاللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ الْخُبُثِ وَالْخَبَائِثِ
Allahumma inni a'udhu bika minal-khubuthi wal-khaba'ith
Translation
O Allah, I seek Your protection from male and female devils.
Recite before entering the bathroom/toilet — placing the left foot first. Evil jinn inhabit dirty places, and this dua is a shield. After exiting, say: "Ghufranaka (Your forgiveness, O Lord)" (Abu Dawud).
