There was a man who fought most bravely of all the Muslims on behalf of the Muslims in a battle (Ghazwa) in the company of the Prophet. The Prophet ﷺ looked at him and said. "If anyone would like to see a man from the people of the Fire, let him look at this (brave man)." On that, a man from the People (Muslims) followed him, and he was in that state i.e., fighting fiercely against the pagans till he was wounded, and then he hastened to end his life by placing his sword between his breasts (and pressed it with great force) till it came out between his shoulders. Then the man (who was watching that person) went quickly to the Prophet ﷺ and said, "I testify that you are Messenger of Allah ﷺ!" The Prophet ﷺ asked him, "Why do you say that?" He said, "You said about so-and-so, 'If anyone would like to see a man from the people of the Fire, he should look at him.' He fought most bravely of all of us on behalf of the Muslims and I knew that he would not die as a Muslim (Martyr). So when he got wounded, he hastened to die and committed suicide." There-upon the Prophet ﷺ said, "A man may do the deeds of the people of the Fire while in fact he is one of the people of Paradise, and he may do the deeds of the people of Paradise while in fact he belongs to the people of Fire, and verily, (the rewards of) the deeds are decided by the last actions (deeds)".  

عَنِ الْمُسْلِمِينَ فِي غَزْوَةٍ غَزَاهَا مَعَ النَّبِيِّ ﷺ فَنَظَرَ النَّبِيُّ ﷺ فَقَالَ مَنْ أَحَبَّ أَنْ يَنْظُرَ إِلَى الرَّجُلِ مِنْ أَهْلِ النَّارِ فَلْيَنْظُرْ إِلَى هَذَا فَاتَّبَعَهُ رَجُلٌ مِنَ الْقَوْمِ وَهْوَ عَلَى تِلْكَ الْحَالِ مِنْ أَشَدِّ النَّاسِ عَلَى الْمُشْرِكِينَ حَتَّى جُرِحَ فَاسْتَعْجَلَ الْمَوْتَ فَجَعَلَ ذُبَابَةَ سَيْفِهِ بَيْنَ ثَدْيَيْهِ حَتَّى خَرَجَ مِنْ بَيْنِ كَتِفَيْهِ فَأَقْبَلَ الرَّجُلُ إِلَى النَّبِيِّ ﷺ مُسْرِعًا فَقَالَ أَشْهَدُ أَنَّكَ رَسُولُ اللَّهِ فَقَالَ وَمَا ذَاكَ قَالَ قُلْتَ لِفُلاَنٍ مَنْ أَحَبَّ أَنْ يَنْظُرَ إِلَى رَجُلٍ مِنْ أَهْلِ النَّارِ فَلْيَنْظُرْ إِلَيْهِ وَكَانَ مِنْ أَعْظَمِنَا غَنَاءً عَنِ الْمُسْلِمِينَ فَعَرَفْتُ أَنَّهُ لاَ يَمُوتُ عَلَى ذَلِكَ فَلَمَّا جُرِحَ اسْتَعْجَلَ الْمَوْتَ فَقَتَلَ نَفْسَهُ فَقَالَ النَّبِيُّ ﷺ عِنْدَ ذَلِكَ إِنَّ الْعَبْدَ لَيَعْمَلُ عَمَلَ أَهْلِ النَّارِ وَإِنَّهُ مِنْ أَهْلِ الْجَنَّةِ وَيَعْمَلُ عَمَلَ أَهْلِ الْجَنَّةِ وَإِنَّهُ مِنْ أَهْلِ النَّارِ وَإِنَّمَا الأَعْمَالُ بِالْخَوَاتِيمِ  

The Prophet ﷺ looked at a man fighting against the pagans and he was one of the most competent persons fighting on behalf of the Muslims. The Prophet ﷺ said, "Let him who wants to look at a man from the dwellers of the (Hell) Fire, look at this (man)." Another man followed him and kept on following him till he (the fighter) was injured and, seeking to die quickly, he placed the blade tip of his sword between his breasts and leaned over it till it passed through his shoulders (i.e., committed suicide)." The Prophet ﷺ added, "A person may do deeds that seem to the people as the deeds of the people of Paradise while in fact, he is from the dwellers of the (Hell) Fire: and similarly a person may do deeds that seem to the people as the deeds of the people of the (Hell) Fire while in fact, he is from the dwellers of Paradise. Verily, the (results of) deeds done, depend upon the last actions."  

نَظَرَ النَّبِيُّ ﷺ إِلَى رَجُلٍ يُقَاتِلُ الْمُشْرِكِينَ وَكَانَ مِنْ أَعْظَمِ الْمُسْلِمِينَ غَنَاءً عَنْهُمْ فَقَالَ مَنْ أَحَبَّ أَنْ يَنْظُرَ إِلَى رَجُلٍ مِنْ أَهْلِ النَّارِ فَلْيَنْظُرْ إِلَى هَذَا فَتَبِعَهُ رَجُلٌ فَلَمْ يَزَلْ عَلَى ذَلِكَ حَتَّى جُرِحَ فَاسْتَعْجَلَ الْمَوْتَ فَقَالَ بِذُبَابَةِ سَيْفِهِ فَوَضَعَهُ بَيْنَ ثَدْيَيْهِ فَتَحَامَلَ عَلَيْهِ حَتَّى خَرَجَ مِنْ بَيْنِ كَتِفَيْهِ فَقَالَ النَّبِيُّ ﷺ إِنَّ الْعَبْدَ لَيَعْمَلُ فِيمَا يَرَى النَّاسُ عَمَلَ أَهْلِ الْجَنَّةِ وَإِنَّهُ لَمِنْ أَهْلِ النَّارِ وَيَعْمَلُ فِيمَا يَرَى النَّاسُ عَمَلَ أَهْلِ النَّارِ وَهْوَ مِنْ أَهْلِ الْجَنَّةِ وَإِنَّمَا الأَعْمَالُ بِخَوَاتِيمِهَا  

[Machine] We went out with the Messenger of Allah ﷺ , and when we met the pagans, we fought them until we scattered and some of us were with them in the evening. Both groups were exhausted and tired, except for one man from the Companions of the Prophet ﷺ who didn't get tired or leave any enemies except that he killed them. The people were amazed by his patience, so the Messenger of Allah ﷺ said, "Whoever wants to see a man from the people of Hell, let him look at this man." A man from the people said, "By Allah, I will be the companion of someone like him until I see what will happen." He then got injured and became fearful of death. He took his sword and placed it against his chest and then leaned on it until it came out from his back. The man came to the Messenger of Allah ﷺ and informed him about it, so the Messenger of Allah ﷺ said, "Truly, a person may do deeds apparent to the people in the world, which seem to be the deeds of the people of Paradise, while in fact, he is one of the people of Hell. Also, a person may do deeds apparent to the people in the world, which seem to be the deeds of the people of Hell, while in fact, he is one of the people of Paradise."  

غَزَوْنَا مَعَ رَسُولِ اللهِ ﷺ فَلَمَّا لَقِينَا الْمُشْرِكِينَ قَاتَلْنَاهُمْ حَتَّى تَفَرَّقْنَا وإِيَّاهُمْ عِنْدَ الْمَسَاءِ وَكِلَا الْفَرِيقَيْنِ قَدْ أَعْيَى وَتَعِبَ وَرَجُلٌ مِنْ أَصْحَابِ النَّبِيِّ ﷺ لَمْ يَمَلَّ وَلَمْ يَعْيَ لَمْ يَتْرُكْ شَاذَّةً وَلَا فَاذَّةً لِلْقَوْمِ إِلَّا قَتَلَهَا فَعَجِبَ النَّاسُ مِنْ صَبْرِهِ فَقَالَ رَسُولُ اللهِ ﷺ «مَنْ أَحَبَّ أَنْ يَنْظُرَ إِلَى رَجُلٍ مِنْ أَهْلِ النَّارِ فَلْيَنْظُرْ إِلَى هَذَا» فَقَالَ رَجُلٌ مِنَ النَّاسِ وَاللهِ لَأَكُونَنَّ أَنَا صَاحِبَهُ حَتَّى أَنْظُرَ إِلَى مَا يَصِيرُ فَجُرِحَ فَجَزِعَ مِنَ الْمَوْتِ فَأَخَذَ سَيْفَهُ فَوَضَعَهُ عَلَى كَبِدِهِ ثُمَّ اتَّكَأَ عَلَيْهِ حَتَّى أَنْفَذَهُ مِنْ ظَهْرِهِ فَجَاءَ الرَّجُلُ إِلَى رَسُولِ اللهِ ﷺ فَأَخْبَرَهُ بِذَلِكَ فَقَالَ رَسُولُ اللهِ ﷺ «إِنَّ الْعَبْدَ لَيَعْمَلُ بِطَاعَةِ اللهِ ﷻ فِيمَا يَبْدُو لِلنَّاسِ وَإِنَّهُ لَمَكْتُوبٌ عِنْدَ اللهِ مِنْ أَهْلِ النَّارِ وَإِنَّ الْعَبْدَ لَيَعْمَلُ بِمَعاصِي اللهِ فِيمَا يَبْدُو لِلنَّاسِ وَإِنَّهُ لَمَكْتُوبٌ عِنْدَ اللهِ مِنْ أَهْلِ الْجَنَّةِ»  

" عَنْ سَهْلِ بْنِ سَعْدٍ أَنَّ رَجُلًا كَانَ مِنْ أَعْظَمِ الْمُسْلمينَ غَناءً عَنِ الْمُسْلِمينَ فِى غَزَاةٍ غزَاهَا مَعَ رَسُولِ الله ﷺ ، فَنَظَرَ إِلَيْه رَسُولُ الله ﷺ فَقَالَ: مَنْ أَحَبَّ أَن يَنْظُرَ إِلَى رَجُلٍ مِن أَهْلِ النَّارِ فَليَنْظُرْ إِلَى هَذَا، فَاتَّبَعَهُ رَجُلٌ مِنَ الْقَوْمِ وَهُوَ عَلَى تِلْكَ الْحَالِ منْ أَشَدِّ النَّاسِ عَلَى الْمُشْرِكينَ حَتَّى جُرِحَ فَاسْتَعْجَلَ الْمَوْتَ، فَجَعَلَ ذُبَابَةَ سَيْفِهِ بَيْنَ ثَدْيَيْهِ حَتَّى خَرَجَ مِنْ بَيْنِ كَتِفَيْهِ، فَأَقْبَلَ الرَّجُلُ الَّذِى كَانَ مَعَهُ إِلَى رَسُولِ الله ﷺ مُسْرِعًا، فَقَالَ: إِنِّى أَشْهَدُ أَنَّكَ رَسُولُ الله ﷺ ، فَقَالَ لَهُ رَسُولُ الله ﷺ : مَا ذَاكَ؟ قَالَ: قُلْتَ: مَنْ أَحَبَّ أَنْ يَنْظُرَ إِلَى رَجُلٍ مِنْ أَهْلِ النَّارِ فَلْيَنْظُرْ إِلَى هَذَا، وَكَانَ مِنْ أَعْظَمِنَا غَنَاءً عَنِ الْمُسْلِمِينَ، فَقُلتُ: إِنَّهُ لاَ يَمُوتُ عَلَى ذَلِكَ، فَلَمَّا جُرِح اسْتَعْجَلَ الْمَوْتَ فَقَتَلَ نَفْسَهُ، فَقَالَ رَسُولُ الله ﷺ : إِنَّ الْعَبْدَ لَيَعْمَلُ عَمَلَ أَهْلِ الْجَنَّةِ وَإِنَّهُ لَمِنْ أَهْلِ النَّارِ، وَيَعْمَل عَمَلَ أَهْلِ النَّارِ وَإِنَّهُ لَمِنْ أَهْلِ الْجَنَّةِ، وَإِنَّمَا الأعْمَالُ بِالْخَوَاتِيم ".
