وَعَنْهُ قَالَ: «كَانَ رَسُولُ اَللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: إِذَا دَخَلَ اَلْخَلَاءَ قَالَ: «اَللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنْ اَلْخُبُثِ وَالْخَبَائِثِ»
The Prophet (sallallahu alayhi wa sallam) on entering the lavatory used to say: “O Allah, I seek refuge with You from devils – males and females (or all offensive and wicked things, evil deeds and evil spirits, etc.)”
