Arabic (Original)
حَدَّثَنَا وَكِيعٌ وَأَبُو عَبْدِ الرَّحْمَنِ قَالَا حَدَّثَنَا عُيَيْنَةُ عَنْ أَبِيهِ عَنْ أَبِي بَكْرَةَ قَالَ قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مَنْ قَتَلَ مُعَاهَدًا فِي غَيْرِ كُنْهِهِ حَرَّمَ اللَّهُ عَلَيْهِ الْجَنَّةَ قَالَ أَبُو عَبْد الرَّحْمَنِ كُنْهُهُ حَقٌّ.
English Translation
Waki' and Abu 'Abd al-Rahman narrated to us, both saying: 'Uyayna narrated to us, from his father, from Abu Bakra, who said: The Messenger of God, peace and blessings be upon him, said: "Whoever kills a person under covenant without proper cause, God has forbidden Paradise to him." Abu 'Abd al-Rahman said: "kunhihi" means "rightful cause."
