أَخْبَرَنَا مُحَمَّدُ بْنُ مَنْصُورٍ، قَالَ حَدَّثَنَا سُفْيَانُ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " إِنَّ اللَّهَ عَزَّ وَجَلَّ يَعْجَبُ مِنْ رَجُلَيْنِ يَقْتُلُ أَحَدُهُمَا صَاحِبَهُ - وَقَالَ مَرَّةً أُخْرَى لَيَضْحَكُ مِنْ رَجُلَيْنِ يَقْتُلُ أَحَدُهُمَا صَاحِبَهُ - ثُمَّ يَدْخُلاَنِ الْجَنَّةَ " .
Muhammad ibn Mansur informed us; he said: Sufyan narrated to us, from Abu al-Zinad, from al-Araj, from Abu Hurayrah, from the Prophet (peace and blessings of Allah be upon him), who said: Allah, Mighty and Majestic, marvels at two men, one of whom kills the other, and then both enter Paradise. In another narration, it says: Allah laughs at two men, one of whom kills the other, and then both enter Paradise.
Translation notes
The source explicitly gives two wordings: Allah marvels, and in another narration, Allah laughs.
