"Whenever the Messenger of Allah entered the toilet, he would say: 'A'udhu Billahi minal-khubthi wa'l-khaba'ith (I seek refuge with Allah from male and female devils).'" (Using translation from Ibn Mājah 298)
كَانَ نَبِيُّ اللهِ ﷺ إِذَا دَخَلَ الْخَلَاءَ قَالَ أَعُوذُ بِاللهِ مِنَ الْخُبْثِ وَالْخَبَائِثِ
