ذِكْرُ الْخَبَرِ الْمُدْحِضِ قَوْلَ مَنْ زَعَمَ أَنَّ أَوَّلَ هَذَا الْخَبَرِ مَوْقُوفٌ غَيْرُ مُسْنَدٍ
Abu Dharr said (and not the Prophet): If there is not anything like the back of a saddle in front of a man who is praying, then a donkey, a black dog, and a woman cut off his prayer. I asked him: Why has the black dog been specified, distinguishing it from a red, a yellow and a white dog? He replied: My nephew, I also asked the Messenger of Allah ﷺ the same question as you asked me. He said: The black dog is a devil. (Using translation from Abū Dāʾūd 702)
عَنِ النَّبِيِّ ﷺ قَالَ «يَقْطَعُ صَلَاةَ الرَّجُلِ إِذَا لَمْ يَكُنْ بَيْنَ يَدَيْهِ كَآخِرَةِ الرَّحْلِ الْحِمَارُ وَالْكَلْبُ الْأَسْوَدُ وَالْمَرْأَةُ» قَالَ قُلْتُ مَا بَالُ الْأَسْوَدِ مِنَ الْأَحْمَرِ مِنَ الْأَصْفَرِ؟ فَقَالَ سَأَلْتُ رَسُولَ اللَّهِ ﷺ كَمَا سَأَلْتَنِي فَقَالَ «الْأَسْوَدُ شَيْطَانٌ»
