Invocation Upon Entering the Toilet:
Below we are sharing the Supplication before going toilet in Arabic and English.
اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ الْخُبُثِ وَالْخَبَائِثِ
(Before Entering) [I begin with the name of Allah]. (Then) Oh Allah, I seek protection in you from male, and female devils.
[Bismillaah], Allaahumma inni a’oodhu bika minal khubthi wal khabaa’ith.
“Whoever says this will be forgiven, and if he supplicate Allah, his prayer will be answered; if he performs ablution and prays, his prayer will be accepted.”
