((إِذَا سَمِعْتُمْ نُبَاحَ الْكِلاَبِ وَنَهِيقَ الْحَمِيرِ بِاللَّيْلِ فَتَعَوَّذُوا بِاللَّهِ مِنْهُنَّ؛ فَإِنَّهُنَّ يَرَيْنَ مَا لاَ تَرَوْنَ)).
(If you hear the barking of dogs or the braying of asses at night, seek refuge in Allah for they see what you do not.)
Abu Dawud 4/327, Ahmad 3/306. Al-Albani graded it authentic in Sahih Abu Dawud 3/961.
