The Ruling on a Father Killing His Son and His Heirs

Question:
The nature of the Shaykh: If a father kills his son, is he subject to retaliation (qisas) or does he pay the blood money (diyah)?

Answer:
I have previously stated to you that a parent is not subject to retaliation for killing their child; rather, the blood money (diyah) is obligatory upon them, and they are barred from inheriting from it. The blood money is obligatory upon them, and they are excluded from the inheritance from the estate and from the blood money. The killer has no inheritance, neither from the blood money nor from anything else. There is a hadith: "The killer has no share." This is for the protection of souls from being killed, so that one does not covet this person's wealth and then hasten their death by killing them in order to inherit. The Shari'ah dealt with him by the opposite of his intention: if he kills his heir, he does not inherit from him, even if his killing was accidental, as a means of blocking the means to harm (sadd al-dhara'i').
