When you hear a dog barking or a donkey braying in the night, then seek refuge in Allah from them, for surely they have seen what you see not. Reference: Abu Dawud 4/327, Ahmad 3/306. Al-Albani graded it authentic in Sahih Abu Dawud 3/961.

إِذَا سَمِعْتُمْ نُبَاحَ الْكِلاَبِ وَنَهِيقَ الْحَمِيرِ بِاللَّيْلِ فَتَعَوَّذُوا بِاللَّهِ مِنْهُنَّ؛ فَإِنَّهُنَّ يَرَيْنَ مَا لاَ تَرَوْنَ
