[Machine] Cutting off a man's prayer is when there is a woman, a donkey, or a black dog in front of him. So I asked Abu Dharr: "What do you think about a black dog compared to a red dog or a white dog?" He replied: "O nephew, I asked the Messenger of Allah ﷺ just as you asked me, and he said: 'The black dog is a devil.'"
يَقْطَعُ صَلَاةَ الرَّجُلِ إِذَا لَمْ يَكُنْ بَيْنَ يَدَيْهِ مِثْلُ آخِرَةِ الرَّحْلِ الْمَرْأَةُ وَالْحِمَارُ وَالْكَلْبُ الْأَسْوَدُ فَقُلْتُ يَا أَبَا ذَرٍّ أَرَأَيْتَ الْكَلْبَ الْأَسْوَدَ مِنَ الْكَلْبِ الْأَحْمَرِ مِنَ الْكَلْبِ الْأَبْيَضِ؟ قَالَ قَالَ يَا ابْنَ أَخِي إِنِّي سَأَلْتُ رَسُولَ اللهِ ﷺ كَمَا سَأَلْتَنِي فَقَالَ الْكَلْبُ الْأَسْوَدُ شَيْطَانٌ
