Sahih al-Bukhari 6606
Narrated Abu Huraira:
We witnessed along with Allah's Messenger (ﷺ) the Khaibar (campaign). Allah's Messenger (ﷺ) told his 
companions about a man who claimed to be a Muslim, "This man is from the people of the Fire." 
When the battle started, the man fought very bravely and received a great number of wounds and got 
crippled. On that, a man from among the companions of the Prophet (ﷺ) came and said, "O Allah's 
Apostle! Do you know what the man you described as of the people of the Fire has done? He has 
fought very bravely for Allah's Cause and he has received many wounds." The Prophet (ﷺ) said, "But he 
is indeed one of the people of the Fire." Some of the Muslims were about to have some doubt about 
that statement. So while the man was in that state, the pain caused by the wounds troubled him so 
much that he put his hand into his quiver and took out an arrow and committed suicide with it. Off 
went some men from among the Muslims to Allah's Messenger (ﷺ) and said, "O Allah's Messenger (ﷺ)! Allah has 
made your statement true. So-and-so has committed suicide." Allah's Messenger (ﷺ) said, "O Bilal! Get up 
and announce in public: None will enter Paradise but a believer, and Allah may support this religion 
(Islam) with a wicked man."
حَدَّثَنَا حِبَّانُ بْنُ مُوسَى، أَخْبَرَنَا عَبْدُ اللَّهِ، أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ شَهِدْنَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم خَيْبَرَ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم لِرَجُلٍ مِمَّنْ مَعَهُ يَدَّعِي الإِسْلاَمَ ‏"‏ هَذَا مِنْ أَهْلِ النَّارِ ‏"‏‏.‏ فَلَمَّا حَضَرَ الْقِتَالُ قَاتَلَ الرَّجُلُ مِنْ أَشَدِّ الْقِتَالِ، وَكَثُرَتْ بِهِ الْجِرَاحُ فَأَثْبَتَتْهُ، فَجَاءَ رَجُلٌ مِنْ أَصْحَابِ النَّبِيِّ صلى الله عليه وسلم فَقَالَ يَا رَسُولَ اللَّهِ أَرَأَيْتَ الَّذِي تَحَدَّثْتَ أَنَّهُ مِنْ أَهْلِ النَّارِ قَدْ قَاتَلَ فِي سَبِيلِ اللَّهِ مِنْ أَشَدِّ الْقِتَالِ، فَكَثُرَتْ بِهِ الْجِرَاحُ‏.‏ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏"‏ أَمَا إِنَّهُ مِنْ أَهْلِ النَّارِ ‏"‏‏.‏ فَكَادَ بَعْضُ الْمُسْلِمِينَ يَرْتَابُ فَبَيْنَمَا هُوَ عَلَى ذَلِكَ إِذْ وَجَدَ الرَّجُلُ أَلَمَ الْجِرَاحِ فَأَهْوَى بِيَدِهِ إِلَى كِنَانَتِهِ، فَانْتَزَعَ مِنْهَا سَهْمًا فَانْتَحَرَ بِهَا، فَاشْتَدَّ رِجَالٌ مِنَ الْمُسْلِمِينَ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم فَقَالُوا يَا رَسُولَ اللَّهِ صَدَّقَ اللَّهُ حَدِيثَكَ، قَدِ انْتَحَرَ فُلاَنٌ فَقَتَلَ نَفْسَهُ‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ يَا بِلاَلُ قُمْ فَأَذِّنْ، لاَ يَدْخُلُ الْجَنَّةَ إِلاَّ مُؤْمِنٌ، وَإِنَّ اللَّهَ لَيُؤَيِّدُ هَذَا الدِّينَ بِالرَّجُلِ الْفَاجِرِ ‏"‏‏.‏
