اللَّهَ عَزَّ وَجَلَّ يَعْجَبُ مِنْ رَجُلَيْنِ يَقْتُلُ أَحَدُهُمَا صَاحِبَهُ - وَقَالَ مَرَّةً أُخْرَى لَيَضْحَكُ مِنْ رَجُلَيْنِ يَقْتُلُ أَحَدُهُمَا صَاحِبَهُ - ثُمَّ يَدْخُلاَنِ الْجَنَّةَ "
It was narrated from Abu Hurairah that the Prophet (ﷺ) said: "Allah, the Mighty and Sublime, likes it when there are two men, one of whom killed the other, then they both enter Paradise." And another time he said: "He laughs at two men, one of whom killed the other, then they both entered Paradise."
