أَخْبَرَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدِ بْنِ تَمِيمٍ، قَالَ: حَدَّثَنَا حَجَّاجٌ، قَالَ: أَخْبَرَنِي شُعْبَةُ، عَنْ أَبِي عِمْرَانَ الْجَوْنِيِّ
قَالَ: قَالَ جُنْدَبٌ حَدَّثَنِي فُلَانٌ، أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَالَ: «يَجِيءُ الْمَقْتُولُ بِقَاتِلِهِ يَوْمَ الْقِيَامَةِ فَيَقُولُ سَلْ هَذَا فِيمَ قَتَلَنِي فَيَقُولُ قَتَلْتُهُ عَلَى مُلْكِ فُلَانٍ». قَالَ جُنْدَبٌ فَاتَّقِهَا
“Jundab said: ‘So and so told me that the Messenger of Allah (sallallahu alayhi wa sallam) said: The slain will bring his killer on the Day of Resurrection and will say: Ask him why he killed me. He will say: I killed him defending the kingdom of so and so.’” Jundab said: “So be careful.”
