229
The Prophet ﷺ said:
إِذَا سَمِعْتُمْ نُبَاحَ الْكِلاَبِ وَنَهِيقَ الْحُمُرِ بِاللَّيْلِ فَتَعَوَّذُوا بِاللَّهِ فَإِنَّهُنَّ يَرَيْنَ مَا لاَ تَرَوْنَ
Idha sami'tum nubahal-kilabi wanahiqal-humuri bil-layli fata'awwadhu billahi fa innahunna yarayna ma la tarawna
When you hear dogs barking and donkeys braying at night, seek refuge in Allah, for they see what you do not see.
