Hafs reported that the Messenger of Allah(ﷺ) as saying, and the other version of this tradition transmitted through a different chain has: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.
حَدَّثَنَا حَفْصُ بْنُ عُمَرَ، حَدَّثَنَا شُعْبَةُ، ح وَحَدَّثَنَا عَبْدُ السَّلاَمِ بْنُ مُطَهَّرٍ، وَابْنُ، كَثِيرٍ - الْمَعْنَى - أَنَّ سُلَيْمَانَ بْنَ الْمُغِيرَةِ، أَخْبَرَهُمْ عَنْ حُمَيْدِ بْنِ هِلاَلٍ، عَنْ عَبْدِ اللَّهِ بْنِ الصَّامِتِ، عَنْ أَبِي ذَرٍّ، - قَالَ حَفْصٌ - قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم وَقَالاَ عَنْ سُلَيْمَانَ قَالَ أَبُو ذَرٍّ " يَقْطَعُ صَلاَةَ الرَّجُلِ - إِذَا لَمْ يَكُنْ بَيْنَ يَدَيْهِ قِيدُ آخِرَةِ الرَّحْلِ الْحِمَارُ وَالْكَلْبُ الأَسْوَدُ وَالْمَرْأَةُ " . فَقُلْتُ مَا بَالُ الأَسْوَدِ مِنَ الأَحْمَرِ مِنَ الأَصْفَرِ مِنَ الأَبْيَضِ فَقَالَ يَا ابْنَ أَخِي سَأَلْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم كَمَا سَأَلْتَنِي فَقَالَ " الْكَلْبُ الأَسْوَدُ شَيْطَانٌ " .
