Messenger of Allah said: "When a man performs Salat, and there is nothing in front of him like the post of a saddle, or a camel saddle, then his Salat is severed by (passing of) a black dog, a woman, and a donkey." It was said to Abu Dharr: "What is the problem with the black dog rather than the red or white one?" He said: "O my nephew! I asked Messenger of Allah just as you have asked me. He said: 'The black dog is a Shaitan (devil).'"  

قَالَ رَسُولُ اللَّهِ ﷺ إِذَا صَلَّى الرَّجُلُ وَلَيْسَ بَيْنَ يَدَيْهِ كَآخِرَةِ الرَّحْلِ أَوْ كَوَاسِطَةِ الرَّحْلِ قَطَعَ صَلاَتَهُ الْكَلْبُ الأَسْوَدُ وَالْمَرْأَةُ وَالْحِمَارُ فَقُلْتُ لأَبِي ذَرٍّ مَا بَالُ الأَسْوَدِ مِنَ الأَحْمَرِ مِنَ الأَبْيَضِ فَقَالَ يَا ابْنَ أَخِي سَأَلْتَنِي كَمَا سَأَلْتُ رَسُولَ اللَّهِ ﷺ فَقَالَ الْكَلْبُ الأَسْوَدُ شَيْطَانٌ قَالَ وَفِي الْبَابِ عَنْ أَبِي سَعِيدٍ وَالْحَكَمِ بْنِ عَمْرٍو الْغِفَارِيِّ وَأَبِي هُرَيْرَةَ وَأَنَسٍ  

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)   

قَالَ رَسُولُ اللهِ ﷺ يَقْطَعُ صَلَاةَ الرَّجُلِ إِذَا لَمْ يَكُنْ بَيْنَ يَدَيْهِ كَآخِرَةِ الرَّحْلِ الْمَرْأَةُ وَالْحِمَارُ وَالْكَلْبُ الْأَسْوَدُ قُلْتُ مَا بَالُ الْأَسْوَدِ مِنَ الْأَحْمَرِ؟ قَالَ ابْنَ أَخِي سَأَلْتُ رَسُولَ اللهِ ﷺ كَمَا سَأَلْتَنِي فَقَالَ الْكَلْبُ الْأَسْوَدُ شَيْطَانٌ

يَقْطَعُ صَلَاةَ الرَّجُلِ إِذَا لَمْ يَكُنْ بَيْنَ يَدَيْهِ مِثْلُ آخِرَةِ الرَّحْلِ الْمَرْأَةُ وَالْحِمَارُ وَالْكَلْبُ الْأَسْوَدُ قَالَ قُلْتُ لِأَبِي ذَرٍّ مَا بَالُ الْكَلْبِ الْأَسْوَدِ مِنَ الْكَلْبِ الْأَحْمَرِ؟ قَالَ يَا ابْنَأَخِي سَأَلْتُ رَسُولَ اللهِ ﷺ كَمَا سَأَلْتَنِي فَقَالَ الْكَلْبُ الْأَسْوَدُ شَيْطَانٌ  

"يَقْطَعُ صَلاةَ الرَّجُلِ إِذَا لَمْ يَكُنْ بَيْنَ يَدَيْهِ كَمُؤَخَّرَةِ الرَّحْلِ: الْمَرْأَةُ، وَالْحِمَارُ، وَالْكَلْبُ الأَسْوَدُ، قِيلَ: مَا بَالُ الأَسْوَدِ مِنَ الأَحْمَرِ؟ قَالَ: الْكَلْبُ الأَسْوَدُ شَيْطانٌ".
