The Prohibition of Killing
Sunan an-Nasai
أَخْبَرَنَا مُحَمَّدُ بْنُ الْعَلاَءِ، قَالَ حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ مُسْلِمٍ، عَنْ مَسْرُوقٍ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " لاَ أُلْفِيَنَّكُمْ تَرْجِعُونَ بَعْدِي كُفَّارًا يَضْرِبُ بَعْضُكُمْ رِقَابَ بَعْضٍ لاَ يُؤْخَذُ الرَّجُلُ بِجَرِيرَةِ أَبِيهِ وَلاَ بِجَرِيرَةِ أَخِيهِ " . هَذَا الصَّوَابُ .
It was narrated that Masruq said: "The Messenger of Allah [SAW] said: 'I do not want to see you after I am gone reverting to disbelievers, striking the necks of one another (killing one another). No man is punished for the crime of his father, or the crime of his brother.'" This is correct.
