حَدَّثَنَا قُتَيْبَةُ بْنُ سَعِيدٍ حَدَّثَنَا يَعْقُوبُ وَهُوَ ابْنُ عَبْدِ الرَّحْمَنِ الْقَارِيُّ حَيٌّ مِنْ الْعَرَبِ عَنْ أَبِي حَازِمٍ عَنْ سَهْلِ بْنِ سَعْدٍ السَّاعِدِيِّ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ الْتَقَى هُوَ وَالْمُشْرِكُونَ فَاقْتَتَلُوا فَلَمَّا مَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِلَى عَسْكَرِهِ وَمَالَ الْآخَرُونَ إِلَى عَسْكَرِهِمْ وَفِي أَصْحَابِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ رَجُلٌ لَا يَدَعُ لَهُمْ شَاذَّةً إِلَّا اتَّبَعَهَا يَضْرِبُهَا بِسَيْفِهِ فَقَالُوا مَا أَجْزَأَ مِنَّا الْيَوْمَ أَحَدٌ كَمَا أَجْزَأَ فُلَانٌ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَمَا إِنَّهُ مِنْ أَهْلِ النَّارِ فَقَالَ رَجُلٌ مِنْ الْقَوْمِ أَنَا صَاحِبُهُ أَبَدًا قَالَ فَخَرَجَ مَعَهُ كُلَّمَا وَقَفَ وَقَفَ مَعَهُ وَإِذَا أَسْرَعَ أَسْرَعَ مَعَهُ قَالَ فَجُرِحَ الرَّجُلُ جُرْحًا شَدِيدًا فَاسْتَعْجَلَ الْمَوْتَ فَوَضَعَ نَصْلَ سَيْفِهِ بِالْأَرْضِ وَذُبَابَهُ بَيْنَ ثَدْيَيْهِ ثُمَّ تَحَامَلَ عَلَى سَيْفِهِ فَقَتَلَ نَفْسَهُ فَخَرَجَ الرَّجُلُ إِلَى رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ 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 حَتَّى جُرِحَ جُرْحًا شَدِيدًا فَاسْتَعْجَلَ الْمَوْتَ فَوَضَعَ نَصْلَ سَيْفِهِ بِالْأَرْضِ وَذُبَابَهُ بَيْنَ ثَدْيَيْهِ ثُمَّ تَحَامَلَ عَلَيْهِ فَقَتَلَ نَفْسَهُ فَقَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ عِنْدَ ذَلِكَ إِنَّ الرَّجُلَ لِيَعْمَلُ عَمَلَ أَهْلِ الْجَنَّةِ فِيمَا يَبْدُو لِلنَّاسِ وَهُوَ مِنْ أَهْلِ النَّارِ وَإِنَّ الرَّجُلَ لِيَعْمَلُ عَمَلَ أَهْلِ النَّارِ فِيمَا يَبْدُو لِلنَّاسِ وَهُوَ مِنْ أَهْلِ الْجَنَّةِ.

It was narrated from Sahl bin Sa'd As-Sa'idi that the Messenger of Allah (s.a.w) and the idolators met in battle and fought. When the Messenger of Allah (s.a.w) went back to his camp and the others went back to their camp, there was among the Companions of the Messenger of Allah (s.a.w) a man who killed anyone (of the enemy) who got in his way. They said: "No one has done better today than so-and-so." The Messenger of Allah (s.a.w) said: "Rather he is one of the people of Hell." A man said: 'I am going to follow him.' So he went out with him; every time that man stopped, he stopped with him, and when he hastened, he hastened with him." He said: "The man was badly wounded, so he sought to hasten his death. He put [the handle of] his sword on the ground and its tip in the middle of his chest, then he leaned [on his sword] and killed himself. The man went to the Messenger of Allah (s.a.w) and said: 'I bear witness that you are the Messenger of Allah (s.a.w).' He said: 'Why is that?' He said: '(Regarding) the man who you said was one of the people of the Fire, and the people were astounded by that. I said: 'I will find out about him for you.' So I followed him until he was badly wounded (in the battle), then he sought to hasten his death. He put the handle of his sword on the ground and its tip in the middle of his chest, then he leaned on it and killed himself.' The Messenger of Allah (s.a.w) said: 'A man may do the deeds of [the people of) Paradise, or so it seems to the people, although he is one of the people of the Fire, and a man may do the deeds of [the people of] the Fire, or so it seems to the people, although he is one of the people of Paradise.'"
