Sahih al-Bukhari, Hadith 2898 ⓘ

Narrated Sahl bin Sa`d As-Sa`idi: Allah's Messenger and the pagans faced each other and started fighting. When Allah's Messenger returned to his camp and when the pagans returned to their camp, somebody talked about a man amongst the companions of Allah's Messenger who would follow and kill with his sword any pagan going alone. He said, "Nobody did his job (i.e. fighting) so properly today as that man." Allah's Messenger said, "Indeed, he is amongst the people of the (Hell) Fire." A man amongst the people said, "I shall accompany him (to watch what he does)" Thus he accompanied him, and wherever he stood, he would stand with him, and wherever he ran, he would run with him. Then the (brave) man got wounded seriously and he decided to bring about his death quickly. He planted the blade of the sword in the ground directing its sharp end towards his chest between his two breasts. Then he leaned on the sword and killed himself. The other man came to Allah's Messenger and said, "I testify that you are Allah's Messenger." The Prophet asked, "What has happened?" He replied, "(It is about) the man whom you had described as one of the people of the (Hell) Fire. The people were greatly surprised at what you said, and I said, 'I will find out his reality for you.' So, I came out seeking him. He got severely wounded, and hastened to die by slanting the blade of his sword in the ground directing its sharp end towards his chest between his two breasts. Then he eased on his sword and killed himself." when Allah's Messenger said, "A man may seem to the people as if he were practising the deeds of the people of Paradise while in fact he is from the people of the Hell) Fire, another may seem to the people as if he were practicing the deeds of the people of Hell (Fire), while in fact he is from the people of Paradise."

حَدَّثَنَا قُتَيْبَةُ، حَدَّثَنَا يَعْقُوبُ بْنُ عَبْدِ الرَّحْمَنِ، عَنْ أَبِي حَازِمٍ، عَنْ سَهْلِ بْنِ سَعْدٍ السَّاعِدِيِّ ـ رضى الله عنه أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم الْتَقَى هُوَ وَالْمُشْرِكُونَ فَاقْتَتَلُوا، فَلَمَّا مَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِلَى عَسْكَرِهِ، وَمَالَ الآخَرُونَ إِلَى عَسْكَرِهِمْ، وَفِي أَصْحَابِ رَسُولِ اللَّهِ صلى الله عليه وسلم رَجُلٌ لاَ يَدَعُ لَهُمْ شَاذَّةً وَلاَ فَاذَّةً إِلاَّ اتَّبَعَهَا يَضْرِبُهَا بِسَيْفِهِ، فَقَالَ مَا أَجْزَأَ مِنَّا الْيَوْمَ أَحَدٌ كَمَا أَجْزَأَ فُلاَنٌ‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ أَمَا إِنَّهُ مِنْ أَهْلِ النَّارِ ‏"‏‏.‏ فَقَالَ رَجُلٌ مِنَ الْقَوْمِ أَنَا صَاحِبُهُ‏.‏ قَالَ فَخَرَجَ مَعَهُ كُلَّمَا وَقَفَ وَقَفَ مَعَهُ، وَإِذَا أَسْرَعَ أَسْرَعَ مَعَهُ قَالَ فَجُرِحَ الرَّجُلُ جُرْحًا شَدِيدًا، فَاسْتَعْجَلَ الْمَوْتَ، فَوَضَعَ نَصْلَ سَيْفِهِ بِالأَرْضِ وَذُبَابَهُ بَيْنَ ثَدْيَيْهِ، ثُمَّ تَحَامَلَ عَلَى سَيْفِهِ، فَقَتَلَ نَفْسَهُ، فَخَرَجَ الرَّجُلُ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالَ أَشْهَدُ أَنَّكَ رَسُولُ اللَّهِ‏.‏ قَالَ ‏"‏ وَمَا ذَاكَ ‏"‏‏.‏ قَالَ الرَّجُلُ الَّذِي ذَكَرْتَ آنِفًا أَنَّهُ مِنْ أَهْلِ النَّارِ، فَأَعْظَمَ النَّاسُ ذَلِكَ‏.‏ فَقُلْتُ أَنَا لَكُمْ بِهِ‏.‏ فَخَرَجْتُ فِي طَلَبِهِ، ثُمَّ جُرِحَ جُرْحًا شَدِيدًا، فَاسْتَعْجَلَ الْمَوْتَ، فَوَضَعَ نَصْلَ سَيْفِهِ فِي الأَرْضِ وَذُبَابَهُ بَيْنَ ثَدْيَيْهِ، ثُمَّ تَحَامَلَ عَلَيْهِ، فَقَتَلَ نَفْسَهُ‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم عِنْدَ ذَلِكَ ‏"‏ إِنَّ الرَّجُلَ لَيَعْمَلُ عَمَلَ أَهْلِ الْجَنَّةِ فِيمَا يَبْدُو لِلنَّاسِ، وَهْوَ مِنْ أَهْلِ النَّارِ، وَإِنَّ الرَّجُلَ لَيَعْمَلُ عَمَلَ أَهْلِ النَّارِ فِيمَا يَبْدُو لِلنَّاسِ، وَهْوَ مِنْ أَهْلِ الْجَنَّةِ ‏"‏‏.‏
