لَا يَرِثُهُ وَ إِنْ كَانَ لِلْقَاتِلِ ابْنٌ وَرِثَ الْجَدَّ الْمَقْتُولَ.
Hadith.5683 - Safwan ibn Yahya narrated from Ibn Abi Umayr, from Jamil, from one of the two Imams (peace be upon them), regarding a man who killed his father. Imam (as) said: "He does not inherit from him. However, if the killer has a son, the son inherits from the murdered grandfather."
