It was narrated that Abu 'Imran Al-Jawni said: "Jundab said: 'So and so told me that the Messenger of Allah [SAW] said: The slain will bring his killer on the Day of Resurrection and will say: Ask him why he killed me.

أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدِ بْنِ تَمِيمٍ، قَالَ حَدَّثَنَا حَجَّاجٌ، قَالَ أَخْبَرَنِي شُعْبَةُ، عَنْ أَبِي عِمْرَانَ الْجَوْنِيِّ، قَالَ قَالَ جُنْدَبٌ حَدَّثَنِي فُلاَنٌ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ ‏ "‏ يَجِيءُ الْمَقْتُولُ بِقَاتِلِهِ يَوْمَ الْقِيَامَةِ فَيَقُولُ سَلْ هَذَا فِيمَ قَتَلَنِي فَيَقُولُ قَتَلْتُهُ عَلَى مُلْكِ فُلاَنٍ ‏" ‏ ‏.‏ قَالَ جُنْدَبٌ فَاتَّقِهَا ‏.‏ 85
