Arabic Text
حَدَّثَنَا سُفْيَانُ عَنْ أَبِي الزِّنَادِ عَنِ الْأَعْرَجِ عَنْ أَبِي هُرَيْرَةَ يَبْلُغُ بِهِ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِنَّ اللَّهَ عَزَّ وَجَلَّ لَيَضْحَكُ مِنْ الرَّجُلَيْنِ قَتَلَ أَحَدُهُمَا الْآخَرَ يَدْخُلَانِ الْجَنَّةَ جَمِيعًا يَقُولُ كَانَ كَافِرًا قَتَلَ مُسْلِمًا ثُمَّ إِنَّ الْكَافِرَ أَسْلَمَ قَبْلَ أَنْ يَمُوتَ فَأَدْخَلَهُمَا اللَّهُ عَزَّ وَجَلَّ الْجَنَّةَ
English Translation
It was narrated from Abu Hurayra (رضي الله عنه) — via Sufyan, from Abu al-Zinad, from al-A'raj — traced to the Prophet ﷺ: 'Indeed Allah (عز وجل) laughs [in a manner befitting His majesty] at two men: one of whom killed the other, yet both enter Paradise together. [The explanation:] One was a disbeliever who killed a Muslim. Then the disbeliever accepted Islam before he died — and so Allah (عز وجل) admitted them both into Paradise.'
