The Book of Menstruation
3/32. Chapter:
What should be said when entering the area in which one relieves himself
Sahih Muslim
وَحَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ، وَزُهَيْرُ بْنُ حَرْبٍ، قَالاَ حَدَّثَنَا إِسْمَاعِيلُ، - وَهُوَ ابْنُ عُلَيَّةَ - عَنْ عَبْدِ الْعَزِيزِ، بِهَذَا الإِسْنَادِ وَقَالَ " أَعُوذُ بِاللَّهِ مِنَ الْخُبْثِ وَالْخَبَائِثِ " .
This hadith is also transmitted by 'Abd al-'Aziz with the same chain of transmitters, and the words are: I seek refuge with Allah from the wicked and noxious things.
