Sahih Muslim — The Book of Faith — Hadith No: 305
وَحَدَّثَنَا مُحَمَّدُ بْنُ رَافِعٍ، وَعَبْدُ بْنُ حُمَيْدٍ، جَمِيعًا عَنْ عَبْدِ الرَّزَّاقِ، - قَالَ ابْنُ رَافِعٍ حَدَّثَنَا عَبْدُ الرَّزَّاقِ، - أَخْبَرَنَا مَعْمَرٌ، عَنِ الزُّهْرِيِّ، عَنِ ابْنِ الْمُسَيَّبِ، عَنْ أَبِي هُرَيْرَةَ، قَالَ شَهِدْنَا مَعَ رَسُولِ اللَّهِ صلى الله عليه وسلم حُنَيْنًا فَقَالَ لِرَجُلٍ مِمَّنْ يُدْعَى بِالإِسْلاَمِ " هَذَا مِنْ أَهْلِ النَّارِ " فَلَمَّا حَضَرْنَا الْقِتَالَ قَاتَلَ الرَّجُلُ قِتَالاً شَدِيدًا فَأَصَابَتْهُ جِرَاحَةٌ فَقِيلَ يَا رَسُولَ اللَّهِ الرَّجُلُ الَّذِي قُلْتَ لَهُ آنِفًا " إِنَّهُ مِنْ أَهْلِ النَّارِ " فَإِنَّهُ قَاتَلَ الْيَوْمَ قِتَالاً شَدِيدًا وَقَدْ مَاتَ . فَقَالَ النَّبِيُّ صلى الله عليه وسلم " إِلَى النَّارِ " فَكَادَ بَعْضُ الْمُسْلِمِينَ أَنْ يَرْتَابَ فَبَيْنَمَا هُمْ عَلَى ذَلِكَ إِذْ قِيلَ إِنَّهُ لَمْ يَمُتْ وَلَكِنَّ بِهِ جِرَاحًا شَدِيدًا فَلَمَّا كَانَ مِنَ اللَّيْلِ لَمْ يَصْبِرْ عَلَى الْجِرَاحِ فَقَتَلَ نَفْسَهُ فَأُخْبِرَ النَّبِيُّ صلى الله عليه وسلم بِذَلِكَ فَقَالَ " اللَّهُ أَكْبَرُ أَشْهَدُ أَنِّي عَبْدُ اللَّهِ وَرَسُولُهُ " . ثُمَّ أَمَرَ بِلاَلاً فَنَادَى فِي النَّاسِ " إِنَّهُ لاَ يَدْخُلُ الْجَنَّةَ إِلاَّ ن��فْسٌ مُسْلِمَةٌ وَإِنَّ اللَّهَ يُؤَيِّدُ هَذَا الدِّينَ بِالرَّجُلِ الْفَاجِرِ " .
Translation
It is narrated on the authority of Abu Huraira:We participated in the Battle of Hunain along with the Messenger of Allah (ﷺ). He (the Holy Prophet) said about a man who claimed to be a Muslim that he was one of the denizens of the Fire (of Hell). When we were in the thick of the battle that man fought desperately and was wounded. It was said: Messenger of Allah, the person whom you at first called as the denizen of Fire fought desperately and died. Upon this the Messenger of Allah (ﷺ) remarked: He was doomed to the Fire (of Hell). Some men were on the verge of doubt (about his fate) when it was said that he was not dead but fatally wounded. When it was night he could not stand the (pain of his) wound and killed himself. The Apostle (ﷺ) was informed of that. He (the Holy Prophet) observed: Allah is Great, I bear testimony to the fact that I am the servant of Allah and His messenger. He then commanded Bilal to announce to the people that none but a Muslim would enter Paradise. Verily Allah helps this faith even by a sinful person
