Sahih Muslim Book - 1, Hadith - 305

و حَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ وَعَبْدُ بْنُ حُمَيْدٍ جَمِيعًا عَنْ عَبْدِ الرَّزَّاقِ قَالَ ابْنُ رَافِعٍ حَدَّثَنَا عَبْدُ الرَّزَّاقِ أَخْبَرَنَا مَعْمَرٌ عَنْ الزُّهْرِيِّ عَنْ ابْنِ الْمُسَيَّبِ عَنْ أَبِي هُرَيْرَةَ قَالَ شَهِدْنَا مَعَ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ حُنَيْنًا فَقَالَ لِرَجُلٍ مِمَّنْ يُدْعَى بِالْإِسْلَامِ هَذَا مِنْ أَهْلِ النَّارِ فَلَمَّا حَضَرْنَا الْقِتَالَ قَاتَلَ الرَّجُلُ قِتَالًا شَدِيدًا فَأَصَابَتْهُ جِرَاحَةٌ فَقِيلَ يَا رَسُولَ اللَّهِ الرَّجُلُ الَّذِي قُلْتَ لَهُ آنِفًا إِنَّهُ مِنْ أَهْلِ النَّارِ فَإِنَّهُ قَاتَلَ الْيَوْمَ قِتَالًا شَدِيدًا وَقَدْ مَاتَ فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِلَى النَّارِ فَكَادَ بَعْضُ الْمُسْلِمِينَ أَنْ يَرْتَابَ فَبَيْنَمَا هُمْ عَلَى ذَلِكَ إِذْ قِيلَ إِنَّهُ لَمْ يَمُتْ وَلَكِنَّ بِهِ جِرَاحًا شَدِيدًا فَلَمَّا كَانَ مِنْ اللَّيْلِ لَمْ يَصْبِرْ عَلَى الْجِرَاحِ فَقَتَلَ نَفْسَهُ فَأُخْبِرَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِذَلِكَ فَقَالَ اللَّهُ أَكْبَرُ أَشْهَدُ أَنِّي عَبْدُ اللَّهِ وَرَسُولُهُ ثُمَّ أَمَرَ بِلَالًا فَنَادَى فِي النَّاسِ أَنَّهُ لَا يَدْخُلُ الْجَنَّةَ إِلَّا نَفْسٌ مُسْلِمَةٌ وَأَنَّ اللَّهَ يُؤَيِّدُ هَذَا الدِّينَ بِالرَّجُلِ الْفَاجِرِ.

It was narrated that Abu Hurairah said: "We were present at (the battle of) Hunain with the Messenger of Allah (s.a.w), and he said of a man who claimed to be a Muslim: 'This is one of the people of the Fire.' When the fighting began, that man fought fiercely, then he was wounded and it was said: 'O Messenger of Allah, the man of whom you said that he is one of the people of the Fire fought fiercely today, and he has died.' The Messenger of Allah (s.a.w) said: 'To the Fire.' Some of the Muslims could hardly believe it, and while they were like that, it was said: 'He has not died, but he is badly wounded.' That night, he could no longer bear the pain, so he killed himself. The Prophet (s.a.w) was informed of that and he said: 'Allahu Akbar! I bear witness that I am the Allah's slave and His Messenger.' Then he ordered Bilal to call out to the people: 'No one will enter Paradise but a Muslim soul, and Allah will support this religion even by means of an evildoer."'
