The texts
حِرْمَانُ الْوَارِثِ مِنَ الْمِيرَاثِ بِالتُّهْمَةِ: ١٢ - لاَ خِلاَفَ بَيْنَ الْفُقَهَاءِ فِي حِرْمَانِ الْقَاتِل عَمْدًا عُدْوَانًا مِنَ الْمِيرَاثِ. وَاخْتَلَفُوا فِي تَوْرِيثِ الْقَاتِل خَطَأً أَوِ الْقَاتِل بِحَقٍّ. فَذَهَبَ الْبَعْضُ إِلَى حِرْمَانِهِمَا، وَذَلِكَ لِتُهْمَةِ اسْتِعْجَال الإِْرْثِ قَبْل أَوَانِهِ. وَالتَّفْصِيل: فِي مُصْطَلَحِ: (إرْثٌ) .
