حَدَّثَنِى عُبَيْدُ اللَّهِ بْنُ مُعَاذٍ الْعَنْبَرِىُّ حَدَّثَنَا أَبِى حَدَّثَنَا شُعْبَةُ عَنْ قَتَادَةَ أَنَّهُ سَمِعَ أَبَا الصِّدِّيقِ النَّاجِىَّ عَنْ أَبِى سَعِيدٍ الْخُدْرِىِّ عَنِ النَّبِىِّ -صلى الله عليه وسلم- « أَنَّ رَجُلاً قَتَلَ تِسْعَةً وَتِسْعِينَ نَفْسًا فَجَعَلَ يَسْأَلُ هَلْ لَهُ مِنْ تَوْبَةٍ فَأَتَى رَاهِبًا فَسَأَلَهُ فَقَالَ لَيْسَتْ لَكَ تَوْبَةٌ. فَقَتَلَ الرَّاهِبَ ثُمَّ جَعَلَ يَسْأَلُ ثُمَّ خَرَجَ مِنْ قَرْيَةٍ إِلَى قَرْيَةٍ فِيهَا قَوْمٌ صَالِحُونَ فَلَمَّا كَانَ فِى بَعْضِ الطَّرِيقِ أَدْرَكَهُ الْمَوْتُ فَنَأَى بِصَدْرِهِ ثُمَّ مَاتَ فَاخْتَصَمَتْ فِيهِ مَلاَئِكَةُ الرَّحْمَةِ وَمَلاَئِكَةُ الْعَذَابِ فَكَانَ إِلَى الْقَرْيَةِ الصَّالِحَةِ أَقْرَبَ مِنْهَا بِشِبْرٍ فَجُعِلَ مِنْ أَهْلِهَا ».

It was narrated from Abu Sa'eed Al-Khudri from the Prophet (s.a.w): "A man killed ninety-nine people, then he started asking whether he could repent. He came to a monk and asked him, and he said: 'You cannot repent,' so he killed the monk. Then he started asking, then he left that town for another town where there were righteous people. When he was part-way there, death overtook him, and he died when he was leaning forward. The Angels of mercy and the Angels of torment disputed over him, but he was closer to the righteous town by a handspan, so he was counted as one of its people."
