case was referred to "Umar bin al Khattab (رضي الله عنه), who ruled that the murderer should pay one hundred camels (as diyah): thirty three-year-old she-camels, thirty four-year-old she-camels and forty five-year-old she camels. He said: And the killer does not inherit anything. Were it not that I heard the Messenger of Allah (ﷺ) say, "No father is to be killed in retaliation for his son,” I would have executed you.
