NASAI 19:
from Anas b. Mālik —
"The Messenger of Allah ﷺ entered Al-Khala' (the toilet) and said: 'Allahumma inni a'uthu bika min al-khubuthi wal-khaba'ith (O Allah, I seek refuge with You from male and female devils)."[1] [1] See Ma'alam As-Sunan by Al-Khattabi. And Al-Khala' is the area one relieves oneself in. It refers to outside or other than that, it should not be understood to mean toilet only.

عن انس بن مالك —
كَانَ رَسُولُ اللَّهِ ﷺ إِذَا دَخَلَ الْخَلاَءَ قَالَ اللَّهُمَّ إِنِّي أَعُوذُ بِكَ مِنَ الْخُبُثِ وَالْخَبَائِثِ
